Tris(1H-benzimidazole-κN³)(oxydiacetato-κ³O,O′,O′′)cobalt(II)

In the title complex, [Co(C₄H₄O₅)(C₇H₆N₂)₃], one tridentate oxydiacetate dianion and three benzimidazole mol­ecules coordinate to the Co^II cation, resulting in a distorted octa­hedral geometry. The oxydiacetate ligand chelates to the Co^II cation with a facial configuration and the Co—O(ether) bond distance is longer than the average Co—O(carbox­yl) bond distance by 0.185 (3) Å. A network of N—H...O hydrogen bonds helps to establish the crystal packing.
