Tetraaquabis(isonicotinamide-N)cobalt(II) terephthalate dihydrate

G.-G. Gao, B. Liu, C.-B. Li and G.-B. Che

Abstract: In the title compound, [Co(C₆H₆N₂O)₂(H₂O)₄](C₈H₄O₄)·2H₂O, the Co^II atom (site symmetry $\\overline{1}$ ) exhibits a slightly distorted trans-CoN₂O₄ octahedral coordination geometry arising from two N-bonded isonicotinamide molecules and four O atoms of water molecules. The uncoordinated centrosymmetric terephthalate anion and uncoordinated water molecules interact with the cation by way of O-HO and N-HO hydrogen bonds, generating a three-dimensional network.
