Synthesis, Crystal Structure and Electrochemical Properties of the Copper(Π) Complex with 1,3-bis(benzimidazol-2-yl)-2-oxopropane

Abstract

A novel complex of Cu(pic)₂ with V-shaped ligand 1,3-bis(benzimidazol-2-yl)-2-o- xopropane (OBB) was synthesized and characterized by elemental analyses and electrical conductivity, IR, UV/visible and ¹H-n.m.r. spectra. The crystal structure of the complex has been determined by the single-crystal X-ray diffraction. In the complex, the Cu(Π) ion is six-coordinated with a N₄O₂ ligand set, resulting in a distorted octahedron.
