【 摘 要 】

The reaction of NiCl2 with fumaric acid and isonicotinamide in a basic solution produces the title complex, [Ni(C6H6N2O)2(H2O)4](C4H2O4). The nickel(II) ion of the complex cation and the fumarate anion are each located on an inversion centre. The NiII ion is coordinated octa­hedrally by four water O atoms and two N atoms of isonicotinamide mol­ecules. The fumarate anion is linked to neighbouring complex cations via Owater—H⋯Ofumarate hydrogen bonds. In the crystal, the complex cations are further linked by O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds, forming a three-dimensional supra­molecular architecture. Hirshfeld surface analysis and two-dimensional fingerprint plots were used to analyse the inter­molecular inter­actions present in the crystal and indicate that the most important contributions for the crystal packing are from H⋯O/O⋯H (41.8%), H⋯H (35.3%) and H⋯C/C⋯H (10.2%) inter­actions.
