Tris(1H-benzimidazole-N³)(oxydiacetato-³O,O',O'')cobalt(II)

L. Cao and D.-J. Xu

Abstract: 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-HO hydrogen bonds helps to establish the crystal packing.
