Summary
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 (mq′bo), 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.
