In the title mononuclear complex, [Ni(C(9)H(4)N(2)O(4))(H(2)O)(5)]·5H(2)O, the Ni(II) atom is six-coordinated by one N atom from a 1H-benzimidazole-5,6-dicarboxyl-ate ligand and by five O atoms from five water mol-ecules and displays a distorted octa-hedral geometry. Inter-molecular O-H⋯O hydrogen-bonding inter-actions among the coordinated water mol-ecules, solvent water mol-ecules and carboxyl O atoms of the organic ligand and additional N-H⋯O hydrogen bonding lead to the formation of a three-dimensional supra-molecular network.
在标题单核配合物[Ni(C₉H₄N₂O₄)(H₂O)₅]·5H₂O中，Ni(II)原子由1H-苯并咪唑-5,6-二羧酸酯配体中的一个N原子以及五个水分子中的五个O原子进行六配位，呈现出扭曲的八面体几何构型。配位水分子、溶剂水分子以及有机配体的羧基O原子之间的分子间O—H⋯O氢键相互作用以及额外的N—H⋯O氢键导致形成了三维超分子网络。
