Synthesis and Properties of Mononuclear and Binuclear Copper(II) Complexes Stabilized by bis‐Benzimidazolyl Ligands

Abstract

The reactions of copper(II) halides with 1,3‐bis(benzimidazol‐2‐yl)benzene and its N‐methylated derivative afforded binuclear and mononuclear complexes, respectively. Mononuclear perchlorate complexes have also been synthesized by the reactions of the aforesaid ligands with hydrated copper perchlorate. The complexes have been characterized by elemental analyses, conductivity and magnetic measurements, TGA studies, IR, electronic, and ESR spectral studies.

Keywords:

• Copper complexes
• Far‐IR spectra
• N‐Heterocycles
• TGA
• ESR spectra
