Abstract

A novel mononuclear complex of the type [Zn(S-2-BIT)3(O-SO3)(CH3OH)2] (where 2-BIT = 2-benzimidazolethiole) has been synthesized and characterized by elemental analysis, FT-IR spectroscopy, UV-Vis spectroscopy, and single crystal-crystal X-ray diffraction. The crystal structure of the complex show that crystallizes in the triclinic P(1 ) ̅space group, with a=9.2946(13) Å, b= 10.1997(13) Å, c= 17.345(3) Å, β=105.494(7)օ, V= 1516.3(4) Å3, R1= 0.0316, wR2= 0.0843. In this complex, the distorted tetrahedral arrangement around the Zinc(II) atom is formed by three sulfur atoms from the 2-MBI ligand and one oxygen atom from the sulfate ion. The crystal lattice structure of the complex also contains two uncoordinated methanol molecules that formed N-H...O and O-H...O intermolecular hydrogen bonds.
