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

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. [ABSTRACT FROM AUTHOR]
