[Zn(L1)Cl2]·DMF (1) and Zn(L2)Cl2 (2) (L1 = 2-[2-(benzimidazol-2-yl)-phenyl]-1-methyl-benzimidazole, L2 = 1,2-bis(1-methyl-benzimidazol-2-yl)benzene) were synthesized and characterized by X-ray single-crystal structure analyses. Complexes 1 and 2 crystallize in the monoclinic space group P21/n. The metal center of Zn2+ is coordinated by two N atoms and two Cl atoms, forming a distorted tetrahedron geometry in each
