Diaquabis(1H-imidazole-N³)bis(4-nitrobenzoato-O)cobalt(II)

T.-G. Xu and D.-J. Xu

Abstract: The title complex, [Co(C₇H₄NO₄)₂(C₃H₄N₂)₂(H₂O)₂], assumes an octahedral coordination geometry with the Co atom located on an inversion center. The overlapped arrangement of parallel imidazole ligands of neighboring complex molecules, with an interplanar distance of 3.555  (14)  Å, suggests the existence of - stacking between imidazole rings.
