Bis[1,3-bis(1H-benzimidazol-2-yl)benzene-N³](succinato-²O,O')zinc(II), a succinate-chelated monomeric compound

F.-Y. Meng, W.-H. Dong and S. W. Ng

Abstract: The succinate dianion in the title 1:2 zinc succinate-1,3-bis(benzimidazol-2-yl)benzene adduct, [Zn(C₄H₄O₄)(C₂₀H₁₄N₄)₂], chelates the Zn atom, which is datively bonded to two of the N-heterocycles in a tetrahedral geometry. The Zn atom and the succinate dianion lie on a twofold rotation axis. The amino -NH group of one heterocycle forms a weak intramolecular hydrogen bond to the carbonyl O atom; that of the second heterocycle engages in an intermolecular N-HN interaction resulting in a linear chain structure.
