A new unique tetranuclear copper(II) complex doubly-bridged by thiocyanate anions [Cu4(mu1,3-NCS)6(dpyam) 4(O2CH)2(H2O)2 (dpyam = di-2-pyridylamine) has been synthesized and characterized by X-ray diffraction methods and magnetic measurements. The “outer” Cu ions, with a CuN3O(S, O) chromophore, have an axially elongated octahedral geometry. The basal plane of these outer Cu(II) ions consist of 2 nitrogen atoms of the dpyam ligand with Cu-N distances of 1.980(2) and 2.008(2) A?, one nitrogen atom of a bridging thiocyanate anion (Cu-N distance 1.961(3) A?) and an oxygen atom of a formate molecule (Cu-O distance 1.977(1) A?). The axial positions are occupied by an oxygen atom of a water molecule (Cu-O distance 2.518(1) A? and by a sulfur atom of a bridging thiocyanate anion at a semi-coordination distance of 3.048(1) A?. The “inner” Cu atoms, with a CuN4(S2) chromophore do also have an axially elongated octahedral geometry. The basal plane is formed by 2 nitrogen atoms of the dpyam ligand with Cu-N distances of 1.995(2) and 2.018(3) A? and two nitrogen atoms of two bridging thiocyanate anions (Cu-N distances 1.946(3), 1.976(3) A?). The axial positions are occupied by two sulfur atoms of two bridging thiocynate anions (Cu-S semi-coordinating distances are 2.875(1) and3.126(1) A?). Each Cu ion is bridged by two mu1,3-NCS anions (in an equatorial-axial bridging mode) forming in this way a zigzag tetranuclear unit. The magnetic susceptibility data of the compound have been investigated between 5 and 200 K. The compound shows a very weak antiferromagnetic interaction between the Cu ions, in agreement with the non-overlapping magnetic orbitals of each Cu ion.

Neutral mononuclear Cu(I) complexes based on 2,2?-dipyridylamine (dpa), formulated as [Cu(dpa)X(PPh3)] (X = Cl (A4), Br (A5), I (A6)), monocationic mononuclear Cu(I) complexes with counterion BF4-, i.e. [Cu(dpa)(PPh3)2](BF4) (A1), Cu(dpa)(DPEphos)(BF4) (A2) and [Cu(dpa)(Binap)](BF4) (A3), where DPEphos = bis [2-(diphenylphosphino) phenyl] ether, Binap = 2,2?-bis(diphenylphosphino)-1,1?-binaphthyl, have been prepared and characterized by 1H NMR, mass spectroscopy and single-crystal X-ray analyses. Their photophysical properties in both CH2Cl2 solution and PMMA (poly(methyl methacrylate)) film have been investigated. All the complexes display a typical metal-to-ligand charge transfer absorption band in the region of 350-400 nm, and a broad and featureless luminescence at room temperature. Specifically, their emission maxima vary from 494 to 562 nm in the PMMA films due to the different electronic characteristics of the auxiliary ligands. Additionally, the thermogravimetric analysis shows that those complexes chelated with diphosphine ligands have a higher thermal stability than those with triphenylphosphine or halides ligands.

1. The effect of 2,2′-dipyridyl ketone and 2,2′-dipyridyl amine on the induction of hepatic microsomal cytochrome P450 (P450) and heme oxygenase was compared, and their effects on five different P450 isoforms (P4501A1, 3A2, 2B1, 2E1 and 2C11) in rat were examined. 2. Treatment of rat with 2,2′-dipyridyl amine resulted in the marked induction of haem oxygenase to about seven-fold of the controls with a decrease in P450 content. 2,2′-Dipyridyl ketone produced concomitant induction of both P450 and haem oxygenase activity in a dose- and time-dependent manner without showing any sex differences. 3. Immunoblot analysis revealed that 2,2′-dipyridyl ketone slightly increased CYP2E1 and CYP3A2 at low doses, but not at high dose levels. There was no effect on P4502C11. P4502B1 was induced by the treatment with 2,2′-dipyridyl ketone in a dose-dependent manner. 4. These results indicate that dipyridyl compounds having different bridges between two aromatic moieties act as differential inducers of hepatic microsomal P450s and haem oxygenase.

The solvent effects on molecular structure, electronic, vibrational and thermochemical properties of 2,2?-Dipyridylamine were investigated by using experimental and theoretical methods. 2,2?-Dipyridylamine molecule was selected for this study intentionally because it has two pyridyl rings connected by amine bridge. This allows to change the stable equilibrium geometry, even the slightest effects. Dichloromethane was chosen as solvent. The reason for this selection is to examine whether the chlorine atoms make hydrogen bonds with the ligand atoms. For this purpose, firstly 2,2?-Dipyridylamine solution was prepared and characterized by FT-IR and FT-Raman spectroscopy. Secondly, crystal structure of 2,2?-Dipyridylamine was obtained to compare with the calculated geometric parameters. The crystal structure was analyzed by Single Crystal X-Ray diffraction methods. Density Functional Theory calculations were conducted with B3LYP functional and 6-31G(d) basis set. The theoretical vibrational properties of optimized geometric structure were computed in vapor and solvation phases. Two different theoretical approaches were discussed, based on the experimental results. It can be seen from the experimental and theoretical studies that the structural, vibrational, thermochemical and electronic properties are dependent on the solvent effects for selected structure. Furthermore, the chlorine atoms of Dichloromethane do not make hydrogen bonds with the ligand atoms.

Both title compounds are polynuclear polymeric complexes with binuclear units. In the former compound, [Ag2(C8H7O 2)2(C10H9N3)] n, the two AgI atoms display distorted square-planar coordinations. This compound contains a twofold axis and a crystallographic inversion centre, and di-2-pyridylamine (DPA) ligands crosslink adjacent binuclear units to form infinite polymeric chains. Crystal packing is stabilized by van der Waals interactions and partial pi-pi stacking interactions between the chains. The latter compound, [Ag2(C7H 4NO4)2(C10H9N 3)]n, contains crystallographic inversion centres and the two Ag’ atoms exhibit two types of distorted square-pyramidal coordination. Ag – Ag argentophilic interactions and Ag – O crosslinking between adjacent binuclear units contribute to form infinite polymeric chains. Weak pi-pi stacking interactions are observed in the polymer chain. Crystal packing is stabilized by C – H…O hydrogen bonds and by weak pi-pi stacking interactions.

The reaction of AgNO3 and sulfobenzoate with neutral ligands led to the formation of three complexes, {[Ag2(4-sb)(Ph 3P)2(3-apy)]·(H2O)}n (1), {[Ag(PPh3)(2-apy)]·[Ag(PPh3)(3-sb)]·(H 2O)}n (2) and [Ag(PPh3)(Hdpa)(4-Hsb)] (3) (4-H2sb = 4-sulfobenzoic acid, PPh3 = triphenylphosphine, 3-apy = 3-aminopyridine, 2-apy = 2-aminopyridine, 3-H2sb = 3-sulfobenzoic acid, Hdpa = 2,2?-dipyridylamine) Complex 1 is a 2D sandwich-like polymer. Complex 2 is a cation-anion species and has a 1D polymer structure. Complex 3 is a monomer. Complexes 1-3 contain the Ag-PPh3 unit and such unit largely hinders the Ag-Ag, pi…pi, Ag…pi, and Ag…C interactions. The experimental results indicated that these three complexes have weaker conductivities than those corresponding silver complexes having abundant weak interactions, especially pi…pi and Ag-Ag interactions, illustrating that the cation-anion species having potential ability of charge transfer can largely promote the conductivity property.

Reactions of CuX (X = Br-, I- or CN-) with various types of 2,2?-dipyridylamine (dpa) derivatives have been performed via a hydrothermal-solvothermal method and the products have been structurally characterized by X-ray crystallography. Four ligands with different coordination motifs were employed in the reactions, including angular N,N,N?,N?-tetra(2-pyridyl)-2,6-pyridinediamine (tppda); linear N,N,N?,N?-tetra(2-pyridyl)-1,4-phenylenediamine (tppa) and N,N,N?,N?-tetra(2-pyridyl)biphenyl-4,4?-diamine (tpbpa); and star-shaped tris-[4-(2,2?-dipyridylamino)-phenyl]amine (tdpa), which yielded eight copper(i) complexes exhibiting different stoichiometries of Cu-dpa and variable coordination modes of dpa. The compound [Cu2(tppda) (mu-I)2]n (1) forms a one dimensional (1D) coordination polymer exclusively through double mu2-I bridges, which arranges to two dimensional (2D) metal-organic frameworks (MOFs) via the face-to-face pi…pi stacking interactions from pyridyl rings. The compound [Cu 6(tppa)(mu3-Br)6]n (2) forms a 2D network linked through multiple mu3-Br bridges. The compound [Cu2(tppa)(mu-CN)2]n (3) is also a 2D MOF containing 1D (CuCN)n chains. The compounds [Cu(tpbpa)Br]n (4) and [Cu4(tpbpa)2(mu-I)4]n (5) display two different 1D assemblies: a zig-zag chain for 4 and a linear structure for 5. The compound [Cu4(tpbpa)(mu-CN)4] n (6) shows a pseudo-4,82 topological net, while the compound [Cu8(tpbpa)(mu-CN)8]n· 2nH2O (7) exhibits a three-dimensional (3D) framework containing a …PM… double helical structure, although both of them contain (CuCN)n chains.

The carboxylato ligands in both compounds 2 and 3 exhibit different coordination modes. One is in a syn, syn eta1: eta1:mu2 bridging mode and the other is in a monoatomic bridging mode. The structure of compound 2 involves a dinuclear unit, with a distorted trigonal bipyramidal geometry around each Cu(II) ion with a CuN2O3 chromophore. Compound 3 contains a non-centrosymmetric unit; the coordination environment around Cu(1) is a distorted square-pyramidal geometry and an intermediate geometry of sp and tbp around the Cu(II) ion. The Cu?Cu separations are 3.061, 3.113 and 3.006 A? for compounds 1, 2 and 3, respectively. The EPR spectra of all three compounds show a broad isotropic signal with a g value around 2.10. The magnetic susceptibility measurements, measured from 5 to 280 K, revealed a moderate ferromagnetic interaction between the Cu(II) ions with a singlet-triplet energy gap (J) of 79.7, 47.8 and 24.1 cm-1, for compounds 1, 2 and 3, respectively. Also a very weak intermolecular antiferromagnetic interaction was observed between the dinuclear units.
