Cobalt(ii), iron(ii), zinc(ii) and palladium(ii) complexes of di-topic 4?-{4-[bis(2-pyridyl)aminomethyl]phenyl}-2,2?:6?, 2?-terpyridine. Synthetic and X-ray structural studies

The di-topic terpy/dpa hybrid ligand, 4?-{4-[bis(2-pyridyl) aminomethyl]phenyl}-2,2?:6?,2?-terpyridine (L), incorporating both 2,2?:6?,2?-terpyridine (terpy) and 2,2?- dipyridylamino domains has been synthesised. The metal complexes [CoLCl 2], [ZnLCl2], [ZnL(CH3CO2) 2], [Fe(L)2(PF6)2] and [Fe(L)(HL)](PF6)0.5(ClO4)2.5 have been isolated. X-ray structures of all five structures show that the respective metal ions preferentially bind to the terpy site of L, with the dpa site in the first four complexes remaining empty. In the fifth complex, which was isolated following the attempted reaction of silver perchlorate with [Fe(L) 2(PF6)2], one dpa site is protonated. The crystal packing of all these species is dominated by extensive pi-interactions. The 5-coordinate zinc(ii) and cobalt(ii) complexes are isostructural and exhibit a 3D network of interactions involving pi-stacking as well as CH…Cl and CH…N hydrogen bonding. Similar interactions occur in the packing of [ZnL(CH3CO2)2] and [Fe(L)(HL)](PF6)0.5(ClO4)2.5 giving rise to 3D arrays. Reaction of palladium(ii) with L yields a product of stoichiometry Pd2LCl4 for which the evidence suggests that palladium binds at both the terpy and dpa domains. Based on this result, addition of [Pd(CH3CN)2Cl2] to [Fe(L) 2](PF6) in acetonitrile yielded a heterometallic complex in which the “free” dpa sites of [Fe(L)2](PF6) are now occupied by palladium ions to form a heterometallic product of type [FePd2(L)2Cl4](PF6) 2·1.5CH3CN.

New dipyridylamine ruthenium complexes for transfer hydrogenation of aryl ketones in water

A new family of cationic organometallic chloro compounds of the type [(arene)Ru(N,N)(Cl)]+ containing N,N-chelating dipyridylamine ligands has been synthesized and isolated as the chloride salts, which are water soluble and stable to hydrolysis. The resulting mononuclear ruthenium complexes catalyze the transfer hydrogenation of aryl ketones in aqueous solution to give the corresponding alcohols with good conversion and interesting recyclability.

Two novel isomeric complexes supported by vanadates {V4O12}: [{Cu(dpa)2}2V4O12] (dpa = 2,2?-dipyridylamine)

Two Cu(II) complexes supported by tetravanadates, [{Cu(dpa)2}2V4O12] (1 and 2), have been synthesized under hydrothermal reactions. Structural analysis indicates that complexes 1 and 2 are isomeric and consist of a cyclic [V4 O12]4 – anion bridged to two [Cu (dpa)2]2 + moieties. Close inspection of complexes 1 and 2 reveals that the [V4 O12]4 – anions adopt chair-like and boat-like configurations respectively, and are coordinated to each Cu(II) ions through a single terminal oxygen atom of two cross vanadium sites. Moreover, Complexes 1 and 2 exhibit trans- and cis-configurations, respectively.

Photophysical and electrochemical properties of new ortho-metalated complexes of rhodium(III) containing 2,2?-dipyridylketone and 2,2?-dipyridylamine. An experimental and theoretical study

Two new ortho-metalated rhodium(iii) complexes of the formula [Rh(ppy) 2(L)]+, ppy = 2-phenylpyridine and L = 2,2?-dipyridylketone (dpk) (1), 2,2?-dipyridylamine (HDPA) (2) have been synthesized and subjected to X-ray diffraction crystal structural, photophysical and electrochemical studies. Density functional theory calculations have also been performed to get rationalizations of the optical orbitals and redox orbitals concerning photophysical and electrochemical data. Complex 1 exhibits the triplet ligand-to-ligand charge transfer ( 3LLCT) [pi(ppy)-pi*(dpk)] phosphorescence at 77K (520 nm) and at room temperature (555 nm), while complex 2 shows triplet ligand centred (3LC) [pi-pi*(ppy)] phosphorescence only at 77K (460 nm). Both complexes 1 and 2 have similar irreversible oxidation potentials (+1.19 V for 1 and +1.15 V for 2 vs. Fc/Fc+). These two complexes show different characteristics in the reduction process: a reversible process occurs for 1 at -1.31 V, while an irreversible process is observed for 2 at -1.85 V.

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.

Blue luminescent organoaluminum compounds: Al(CH3)2(dpa), Al2(CH3)5(dpa)2, Al4(O)2(CH3)6(dpa)2, and Al(pfap)3, dpa = Deprotonated Di-2-pyridylamine, pfap = Deprotonated 2-pentafluoroanilinopyridine

The reactions of Al(CH3)3 with di-2-pyridylamine (dpaH) yielded a mononuclear zwitterion complex, Al(CH3)2(dpa) (1), a dinuclear complex, Al2(CH3)5(dpa) (2), and a tetranuclear complex, Al4(O)2(CH3)6(dpa)2 (3), depending on the stoichiometry and conditions of the reactions. The crystal structures of all three compounds were determined by single-crystal X-ray diffraction analyses. All three compounds emit an intense blue color in solution and the solid state at lambdamax = 475, 445, and 450 nm, respectively, when irradiated by an UV light. Molecular orbital calculations using ab initio methods (Gaussian 94) on dpa, dpaH, and compound 1 were performed which revealed that the aluminum ion in compounds 1-3 plays a key role in stabilizing the complexes and promoting the blue luminescence. The reaction of Al(CH3)3 with 2-pentafluoroanilinopyridine (pfapH) resulted in the formation of a mononuclear octahedral complex, Al(pfap)3 (4). Variable-temperature and COSY 1H NMR established that compound 4 is highly fluxional in solution due to a rapid interconversion of mer and fac isomers, with the mer isomer dominating at low temperature. The structure of the fac isomer of 4 was determined by X-ray diffraction. Compound 4 emits at lambdamax = 409 nm when irradiated by an UV light.

Monomeric, N-functionalised amido complexes of aluminium: Synthesis of [AlCl{NR(8-C9H6N)}2] (R = H or SiMe3) and [Al{N(2-C5H4N)-(2-C5H4N)} 3]

Routes have been devised to a series of aluminium(III) amide complexes containing either of the bulky, N-functionalised amides NR(8-C9H6N)- (R = H or SiMe3) or N(2-C5H4N)2-. Reaction of the lithium amides [{Li(OEt2)[NR(8-C9H6N)]}2] (R = H or SiMe3) with AlCl3 afforded [AlCl(NR(8-C9H6N)]2] (R = H or SiMe3) respectively. The crystal structure of five-co-ordinate [AlCl(NH(8-C9H6N)}2] shows it to be monomeric in the solid state with intramolecular dative interactions between the aluminium centre and both aromatic nitrogen atoms. Treatment of NH(2-C5H4N)2 with [AlH3(NMe3)] yielded the six-co-ordinate complex [Al{N(2-C5H4N)(2-C5H4N)} 3], the crystal structure of which confirms it to be monomeric with intramolecular Al-N (aromatic) dative bonds from one pyridyl functionality of each amide ligand. In solution this complex exhibits fluxional behaviour which has been investigated by variable-temperature 1H NMR spectroscopy.

The target complex has been prepared in one step when [Ag2[B10H10]] was allowed to react with CuCl in the presence of bpa in DMF; the reaction has been performed in air. Copper(I) has been oxidized in air in the presence of bpa to form the tetranuclear cationic complex. The target compound has been studied by IR spectroscopy as well as powder and single crystal X-ray diffractions. The electronic structure and magnetic properties of the complex have been studied by EPR spectroscopy and magnetic susceptibility methods and the obtained data have been compared with those obtained for related tetranuclear bipy-contained copper(II) complexes [Cu4(bipy)4(OH)4][Cu2[B10H10]3]·4CH3CN and {[Cu4(bipy)4(OH)4][B10H10]2(DMSO)2} with the known structures. The magnetic properties of three compounds under study are different; the magnetic moment has been found to increase, to decrease and remain unchanged when increasing temperature.
