✦ Synopsis

The succinate dianion in the title 1:2 zinc succinate-1,3-bis(benzimidazol-2-yl)benzene adduct, [Zn(C 4 H 4 O 4 )-(C 20 H 14 N 4 ) 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-HÁ Á ÁN interaction resulting in a linear chain structure.
