Abstract: The crystal structure of the title compound, [Ni(C₄H₄O₄)(C₇H₆N₂)₂(H₂O)₂]_n, consists of a polymeric Ni^II complex bridged by succinate dianions. The Ni atom is located at a crystallographic inversion center. Both carboxyl groups of the succinate coordinate, in monodentate fashion, to the neighboring Ni^II atoms to form one-dimensional chains, and the chains link to each other via hydrogen bonds between the benzimidazole and carboxyl group to form a two-dimensional supramolecular structure. The overlapped arrangement of parallel benzimidazole ligands, with a separation of 3.350  (3)  Å, suggests the existence of --stacking interactions between adjacent chains.
