Abstract:
The molecular structure of the title complex [ZnBr2(C7H6N2)2] was investigated by X-ray diffraction and IR spectroscopy methods. Molecules of zinc(II) complex crystallize in the triclinic crystal system with cell constants a=7.526(2) Å, b=7.8971(8) Å, c=13.431(1) Å, Z=2 and V=791.3(2) Å3. In the molecular structure, the Zn atom is coordinated tetrahedrally by two Br− anions and two benzimidazole ligands. Intramolecular steric repulsions between Br− anions and benzimidazole groups have been caused to cis configuration around the central metal atom.
