【 摘 要 】

The reaction of cobalt(II) with fumaric acid (H2fum) and isonicotinamide in a basic solution produces the title salt, [Co(C6H6N2O)2(H2O)4](C4H2O4). In the complex cation, the CoII atom, located on an inversion centre, is coordinated by two isonicotinamide and four water mol­ecules in a distorted N2O4 octa­hedral geometry. The fumarate anion is located on another inversion centre and is linked to neighbouring complex cations via O—H⋯O and N—H⋯O hydrogen bonds and weak C—H⋯O hydrogen bonds. In the crystal, the complex cations are further linked by O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds, forming a three-dimensional supra­molecular architectecture. Hirshfeld surface analyses (dnorm surfaces and two-dimensional fingerprint plots) for the title compound are presented and discussed.
