Abstract

Copper(II) complexes CuLCl₂, where L=2-(4-methyl-2-pyridyl)benzimidazole(mpbi); 2-(4-methyl-2-pyridyl)benzothiazole(mpbt); 2-(4-methyl-2-pyridyl)benzoxazole (mpbo); 2-(4-methyl-2-quinolyl)benzoxazole (mqbo); 2-(4-methyl8-quinolyl)benzoxazole (mqbo), and Cu(mpbi)₂Cl₂(H₂O) have been synthesized and characterized by conductivity and magnetic measurements as well as by i.r., electronic and e.s.r. spectra. The ligands are bidentate donors through the pyridine and isoxazole nitrogen atoms. The CuLCl₂ complexes exhibit spectral properties consistent with CuN₂Cl₂ chromophores differing in the degree of tetrahedral distortion, which is found to parallel the steric hindrance near the donor sites. Cu(mpbi)₂ Cl₂(H₂O) is five-coordinate.
