Hexaquacobalt(II) bis(isonicotinate N-oxide): a redetermination and analysis of the hydrogen-bonding interactions

M. Du, X.-J. Zhao and J.-H. Guo

Abstract: In the crystal structure of the title complex, [Co(H₂O)₆](L)₂ (L = isonicotinate N-oxide, C₆H₄NO₃), the Co^II center, on a special position with site symmetry 2/m, is in an elongated octahedral environment composed of six coordinated water molecules. Each water ligand forms two strong O-HO hydrogen bonds with the adjacent isonicotinate N-oxide counter-ions, which lie on mirror planes, forming a three-dimensional hydrogen-bonding supramolecular architecture.
