Synthesis, Spectroscopy and Magnetic Characterization of Five Dinuclear Copper(II) Complexes with 2, 3 or 4-Pyridinemethanol as the Ligand
The synthesis, spectroscopy and magnetic characterization of five new dinuclear copper(II) complexes are described. All five compounds have the general formula [Cu2(L)4(O-R)2](Cl)2 or [Cu2(L)2(Cl)2](Cl)2, in which R = CH3 or H, L=2, 3 or 4-pyridinemethanol as L2, L3 or L4, respectively. The title compounds consist of dinuclear units with bridging methoxo groups in [Cu2(L4)4(O-CH3)2](Cl)2, hydro...
متن کاملSynthesis of Binuclear Copper (II) Complexes with Expanded Porphyrins
The synthesis and characterization of some new binuclear copper (II) complexes, based on the use of large, pyrole-containing macrocycles, the so called "expanded porphyrins", [Cu2(macrocycle)]+4 is described. Electron Spin Resonance (ESR) studies indicate a weak "half-field line", which is characteristic of the Cu(II)-Cu(II) dimer, is observed at about 1600G. The obser...

متن کاملphosphane, P(C7H7)3, as a Tripodal Tetradentate Ligand in Cationic, Five-coordinate Complexes of Platinum(II) and Palladium(II)
Chloride abstraction, using AgPF6, from tri(1cyclohepta-2,4,6-trienyl)phosphane platinum and palladium dichloride, [P]MCl2 [M = Pt (1), Pd (2)], affords the complexes {[P]MCl}PF6 [M = Pt (3), Pd (4)] in good yields. The central metal is coordinated by the chloro ligand, the phosphorus atom and by three η2-C=C units, one of each C7H7 ring. This assignment of a highly symmetrical C3v structure is...
متن کاملrac-Lactide Polymerization with Copper(II) Complexes
Stereocontrolled coordination-insertion polymerization of rac-lactide remains a catalytic challenge despite the large number of studies and the successful marketing of polylactide as a disposable plastic. Although a number successful catalysts have been proposed, a system re-uniting high stereoselectivity with high activity and chemical robustness remains absent. We have been recently concentra...
