Abstract

Copper-based complexes with the general formulas [Cu(L)22_{2}]Cl22_{2} (1) and [Cu22_{2}L22_{2}(μ2μ2\mu_{2}-L)μ2−μ2−\mu_{2-}Cl22_{2}] (2) and a mixed-ligand anionic complex [Cu(L)22_{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. Complexes 1 and 3b were tested for radical scavenging activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) as a free radical. A prominent color change after mixing the solution of complex 1 and DPPH was observed, indicating the efficiency of the compound as antioxidant.
