Bis[1,3‐bis(1H‐benzimidazol‐2‐yl)benzene‐κN3](succinato‐κ2O,O′)zinc(II), a succinate‐chelated monomeric compound

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—H⋯N inter­action resulting in a linear chain structure.
