In the title compound, [Ni(CHNO)(CHO)]·4HO, the Ni cation is octa-hedrally coordinated by one O atom of the succinate anion and three O atoms and two N atoms from an ,,','-tetra-kis-(2-hy-droxy-eth-yl)ethyl-enedi-amine mol-ecule. In the crystal, mol-ecules are linked by O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular architecture. Hirshfeld surface analyses and two-dimensional fingerprint plots were used to analyse the inter-molecular inter-actions present in the crystal, indicating that the most important contributions for the crystal packing are from H⋯H (63.3%) and H⋯O/O⋯H (34.5%) inter-actions.
在标题化合物[Ni(CHNO)(CHO)]·4HO中，镍阳离子由琥珀酸根阴离子的一个氧原子以及来自一个,,','-四-（2-羟乙基）乙二胺分子的三个氧原子和两个氮原子八面体配位。在晶体中，分子通过O-H⋯O和C-H⋯O氢键相连，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，表明晶体堆积的最重要贡献来自H⋯H（63.3%）和H⋯O/O⋯H（34.5%）相互作用。
