The title structure, [Ni(C(14)H(8)N(2)O(4))(H(2)O)(4)]·4H(2)O, contains a mononuclear Ni(II) complex formed by a chelating bidentate Schiff base and by four Ni-bonded water mol-ecules. The Ni(II) atom is in a distorted octa-hedral coordination by two N atoms in a cis disposition [Ni-N = 2.0753 (16) and 2.1048 (16) Å] and by four water O atoms [Ni-O = 2.0500 (15)-2.0822 (15) Å]. The crystal structure is completed by four further non-coordinating water mol-ecules and all constituents are linked in a three-dimensional manner by an extensive system of 16 O-H⋯O hydrogen bonds.
标题结构[Ni(C₁₄H₈N₂O₄)(H₂O)₄]·4H₂O包含一个单核Ni(II)配合物，它由一个螯合双齿席夫碱和四个与Ni键合的水分子形成。Ni(II)原子通过两个处于顺式构型的N原子[Ni-N = 2.0753 (16) 和2.1048 (16) Å]以及四个水分子的O原子[Ni-O = 2.0500 (15)-2.0822 (15) Å]处于扭曲的八面体配位环境中。晶体结构由另外四个非配位水分子完善，所有组分通过一个广泛的16个O-H⋯O氢键体系以三维方式相连。
