tailieunhanh - Antioxidant potential and secondary reactivity of bis{diphenyl(2-pyridyl)phosphino}copper(II) complex

Copper-based complexes with the general formulas [Cu(L)2]Cl2 (1) and [Cu2L2(µ2-L)µ2−Cl2] (2) and a mixed-ligand anionic complex [Cu(L)2 dedtc][LCl] (3b), where L = diphenyl(2-pyridyl)phosphine and dedtc = diethyldithiocarbamate, were synthesized and structurally characterized. X-ray analysis revealed that the coordination environment around the copper atom in complexes 1–3 is distorted tetrahedral. In monomeric complexes 1 and 3b both diphenyl(2-pyridyl) phosphine ligands are monodentate and are coordinated through the P-atom. In complex 3b two phosphine ligands are attached to copper through the P-atom. The third phosphine ligand acts as a bridged ligand, coordinated to the metal centers through the P-atom and N-atom. |
