The reaction of NiCl with fumaric acid and isonicotinamide in a basic solution produces the title complex, Ni(CHNO)(HO). The nickel(II) ion of the complex cation and the fumarate anion are each located on an inversion centre. The Ni ion is coordinated octa-hedrally by four water O atoms and two N atoms of isonicotinamide mol-ecules. The fumarate anion is linked to neighbouring complex cations O-H⋯O 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 supra-molecular architecture. Hirshfeld surface analysis and two-dimensional fingerprint plots were used to analyse the inter-molecular inter-actions 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%) inter-actions.
氯化镍与富马酸和异烟酰胺在碱性溶液中反应生成标题配合物Ni(CHNO)(HO)。配合物阳离子中的镍(II)离子和富马酸根阴离子均位于对称中心上。镍离子由四个水分子的氧原子和两个异烟酰胺分子的氮原子八面体配位。富马酸根阴离子通过O-H⋯O氢键与相邻的配合物阳离子相连。在晶体中，配合物阳离子通过O-H⋯O、N-H⋯O和C-H⋯O氢键进一步相连，形成三维超分子结构。使用 Hirshfeld 表面分析和二维指纹图谱分析晶体中存在的分子间相互作用，结果表明晶体堆积中最重要的贡献来自H⋯O/O⋯H（41.8%）、H⋯H（35.3%）和H⋯C/C⋯H（10.2%）相互作用。
