Abstract
A new distorted square planar (two CuN2 planes making an angle of ~43°) copper(II) complex [Cu(L4)]·0.5EtOH·0.5MeOH (1) of a deprotonated tetradentate pyridine amide ligand [H2L4 = N,N'-bis(2-pyridinecarboxamide)-2,2'-biphenyl] has been synthesized and structurally characterized. Absorption and EPR spectroscopic properties have also been studied. The E½ values (CuII/CuI redox process) of the title complex along with a selected group of structurally characterized CuN4 pyridine amide complexes with systematically varied structural, electronic/steric, and chelate-ring size effects, imposed by the coordinating ligands, have been determined and the observed trend has been rationalized.
