Synthesis, Structure and Magnetic Properties of Copper(II) Complexes of Diphenyl-(1-propylbenzimidazol-2-yl)methanol

摘要

Two types of binuclear copper complexes LCuN3(2) and LCuNO3(2).of bidentate ligand - diphenyl-(1-propylbenzimidazol-2-yl)methanol (HL) in the 4:1 ratio were synthesized. The crystal structure of copper complexes shows a centrosymmetric dimeric binuclear complex with two Cu2+ cations bridged by two oxygen atoms from two organic ligands. In the complexes, a very strong antiferromagnetic exchange interaction between copper atoms is observed.
