چکیده

Pentacoordinated copper(II) complexes were synthesized from tetradentate ligand N,N-bis (2-methyl-N-methylbenzimidazolyl)hexanediamide. Characterization has been done on the basis of elemental analysis, electronic spectra, IR studies, conductance data, magnetic properties, EPR and x-ray studies for the complexes. From analytical data, the stoichiometry of the complexes has been found to be 1:1 metal to ligand ratio. IR spectra and x-ray studies show that the ligand behaves tetradentate through two benzimidazolyl nitrogen and two amide oxygen atoms. The fifth coordination site of the metal is occupied by the anion from metal salt solution.
