Abstract: The title polymeric complex, [Co(-C₄H₂O₄)(C₇H₆N₂)₂(H₂O)₂]_n, displays a one-dimensional chain structure bridged by fumarate dianions. In the crystal structure, the polymeric chains are linked to each other by hydrogen bonds. The overlapped arrangement and the short separation of 3.35  (2)  Å suggest the existence of - stacking between parallel benzimidazole rings. The Co^II atom exists in a centrosymmetric octahedral geometry.
