Abstract

A mixed ligand complex [cis-Dichloro(2-(2-Pyridyl)benzimidazole) (1H-Imidazole)Copper(II)] (1) has been prepared by the reaction of 2-(2-pyridyl)benzimidazole, 1H-imidazole with copper(II)chloride in ethanol medium. The structure of 1 was determined by single crystal X-ray diffraction. The results gives that the complex 1 belongs to monoclinic, space group P21/C with a = 9.3566(19) Å, b = 12.504(3) Å, c = 14.018(3) Å, a = 90°, b = 105.30(3)°,  g = 90°, V = 1582.0(6) Å3, Z = 4 and final R1 = 0.0529, ωR2 = 0.07. The complex molecules form 1D chain structure by the H-Cl-H intermolecular hydrogen bond interaction. The complex exhibits trigonal bipyramidal distorted square based pyramidal (TBDSBP) coordination geometry.
