The use of simple pyrazolate anions and related polychelating acyclic or macrocyclic pyrazolate derivatives as bridging ligands, and occasionally additional blocking ligands, has led to the stereospecific CuII-mediated self-assembly of both homo- and heteroleptic di-mu-pyrazolatodicopper(II) complexes of the metallacyclophane type, so-called dicopper(II) pyrazolenophanes. Besides their unique molecular conformation features and binding abilities toward both neutral molecules and charged anionic species, which have illustrated the putative role of weak intramolecular pi-pi stacking, hydrogen bonding, and coordinative interactions in the self-assembling process, dicopper(II) pyrazolenophanes have been also studied by their magnetic properties. In the present review, a comprehensive investigation has been carried out to determine the influence of subtle structural factors (e.g., trigonal or tetrahedral distortions at the metal center and deviations from planarity of the metallacyclic core) on the strength of the magnetic coupling in these series of homo- and heteroleptic di-mu-pyrazolatodicopper(II) complexes. New magneto-structural correlations have emerged from this study which point out to a dual sigma- and pi-type orbital pathway for the propagation of the electron exchange interaction between the two CuII ions across the two pyrazolate bridges in this unique family of dicopper(II) pyrazolenophanes.

Six new nickel(II) complexes have been synthesized by the reaction of the nitrogen donor coligand 2,2?-dipyridylamine (dipyam) and three different alpha-hydroxyacids (H2L?) with different levels of bulkiness, namely lactic, 2-methyllactic and mandelic acids. Two types of compounds have been obtained: neutral complexes of formula [Ni(HL?)2(dipyam)] and the cationic metal complexes of general formula [Ni(HL?)(dipyam)2](HL?). The structures of the cationic metal complexes have been elucidated by single-crystal X-ray diffraction. The role of the second coordination sphere in the metallosupramolecular organization through different hydrogen-bonding patterns has been analysed. The thermal behaviour of all new compounds has been investigated.

The new complexes of formulae PPh4[Cr(dpa)(ox)2] (1), AsPh4[Cr(dpa)(ox)2] (2), Hdpa[Cr(dpa)(ox)2]·4H2O (3), Rad[Cr(dpa)(ox)2]·H2O (4) and Sr[Cr(dpa)(ox)2]2·8H2O (5) [PPh4=tetraphenylphosphonium cation; AsPh4=tetraphenylarsonium cation; dpa=2,2?-dipyridylamine; ox=oxalate dianion; Rad=2-(4-N-methylpyridinium)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazol-1- oxyl-3-N-oxide] have been prepared and characterised by single-crystal X-ray diffraction. The structures of 1-4 consist of discrete [Cr(dpa)(ox)2]- anions, tetraphenyl- phosphonium (1), tetraphenylarsonium (2), monoprotonated Hdpa (3) and univalent radical (4) cations and uncoordinated water molecules (2-4). The chromium environment in 1-4 is distorted octahedral with Cr-O bond distances between 1.982(2)-1.946(2) A and Cr-N bonds of 2.0716(17)-2.048(3) A. The angles subtended at the chromium atom by the two oxalates are 83.6(2)-81.71(8), whereas the N-Cr-N angles are 87.76(7)-86.24(9). The [Cr(dpa)(ox)2]- unit of 1-4 is also present in 5 but it acts as a chelating ligand through its two oxalato groups towards divalent strontium cations, yielding heterobimetallic zig-zag chains that run parallel to the a axis. Each chain is formed of diamond-shaped units sharing the strontium atoms, while the two other corners are occupied by two crystallographically independent chromium atoms. The [Cr(dpa)(ox)2]- unit in 5 retains the environment observed in 1-4 and the strontium atom is coordinated to eight oxalate oxygens from four oxalate ligands. The two crystallographycally independent chromium centres within each double chain have opposite chirality. However, the adjacent double chains are related by an inversion centre resulting in achiral layers parallel to the ac plane. The magnetic properties of 1-5 have been investigated in the temperature range 1.9-290 K. A quasi Curie law behaviour is observed for 1-3 and 5 in agreement with their crystal structures, whereas a significant antiferromagnetic interaction between the chromium(III) and the radical centre occurs in the case of 4. The synthetic possibilities offered by the use of the heteroleptic species [CrL(ox)2]- (L=alpha-diimine-type ligand) as a ligand towards metal ions is analysed and discussed in the light of the available structural results.

The syntheses, crystal structures, and magnetic properties of three trinuclear, symmetric, heterometal string complexes stabilized by four dipyridylamide (dpa) ligands were explored. MnNiMn(dpa)4Cl2(1), MnPdMn(dpa)4Cl2(2), and MnPtMn(dpa)4Cl2(3) were found to exhibit an approximate D4symmetry and a linear metal framework helically wrapped by four syn?syn-type ligands. The center metal ions bond with the amide part of dpa?in a square-planar environment, and the outer Mn ions bond with Cl?and the pyridyl part of dpa?in a square-pyramidal environment. The magnetic susceptibilities of these three compounds showed antiferromagnetic interactions (2J = ?13.7 cm?1for 1, ?29.7 cm?1for 2, and ?66.2 cm?1for 3 in the Heisenberg exchange framework) between the MnII magnetic centers. The value of 2J increased with increasing atomic number of the central metal ion. The antiferromagnetic properties were further confirmed by electron paramagnetic resonance spectroscopy studies in variable-temperature measurements.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11.

Two binuclear complexes of cobalt(III) have been prepared with 3,3?,4,4?-tetrahydroxy-5,5?-di-tert-butylbenzaldazine (H4thBu) as bis(catecholate) ligand and two different ancillary ligands, 2,2?-bipyridine (bpy) or 2,2?-dipyridylamine (dpa). These compounds were characterized by 1H NMR spectra, electrochemical measurements and UV-Vis spectra. In one case, [Co2(dpa)4(thBu)]2+, electrochemical oxidation of the complexes occurs at the bridges as two closely spaced one-electron couples (E1/2 = 1 mV and 168 mV versus Fc/Fc+). Chemical oxidation of [Co2(dpa)4(thBu)]2+ using Ag+ is observed to occur as a stepwise two-electron process forming [Co2(dpa)4(thBuCat,SQ)]3+ or [Co2(dpa)4(thBuSQ,SQ)]4+ by UV-Vis spectrum. However, [Co2(bpy)4(thBu)]2+ shows no change in electronic spectrum under the same conditions of oxidation. This illustrates the dependence of redox properties of the binuclear Co(III) complexes on the nature of the nitrogen-donor ancillary ligands. In this report we discuss the effect of two different nitrogen-donor ancillary ligands on the0 oxidation behavior of binuclear Co(III) complexes.

Reference of 499-40-1, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11. In a patent, introducing its new discovery.

For a crystal to exhibit nonlinear optical (NLO) activity such as second-harmonic generation (SHG), it must belong to a noncentrosymmetric (NCS) space group. Moreover, for these nonlinear optical (NLO) materials to be suitable for practical uses, the synthesized crystals should be phase-matchable (PM). Previous synthetic research into SHG-active crystals has centered on (i) how to create NCS compounds and/or (ii) how to obtain NCS compounds with high SHG efficiencies. With these tactics, one can synthesize a material with a high SHG efficiency, but the material could be unusable if the material was nonphase-matchable (non-PM). To probe the origin of phase matchability of NCS structures, we present two new chemically similar hybrid compounds within one composition space: (I) [Hdpa]2NbOF5·2H2O and (II) HdpaNbOF4 (dpa = 2,2?-dipyridylamine). Both compounds are NCS and chemically similar, but (I) is non-PM while (II) is PM. Our results indicate – consistent with organic crystallography – the arrangement of the organic molecule within hybrid materials dictates whether the material is PM or non-PM.

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.
