In the title compound, [CdCu(2)(C(12)H(11)N(2)O(5))(2)(H(2)O)(3)]·2H(2)O, the Cu(II) atoms are in a square plane of N(2)O(2) atoms contributed by the tetra-dentate Schiff base trianion. The Cu(II) atoms are coordinated by one phenolate O atom, one imine N atom, one amido N atom and one carboxyl-ate O atom. The Cd(II) atom is connected via the carboxyl-ate groups, forming a heterotrinuclear Cu(II)-Cd(II)-Cu(II) system. The Cd(II) atom is seven-coordinate in a penta-gonal-bipyramidal geometry with four O atoms from two carboxyl-ate groups and three aqua ligands. The heterotrinuclear mol-ecules are linked to the uncoordinated water mol-ecules by O-H⋯O hydrogen bonds into a three-dimensional framework.
在标题化合物[CdCu₂(C₁₂H₁₁N₂O₅)₂(H₂O)₃]·2H₂O中，Cu(II)原子位于由四齿席夫碱三阴离子提供的N₂O₂原子构成的正方形平面内。Cu(II)原子由一个酚盐O原子、一个亚胺N原子、一个酰胺N原子和一个羧酸盐O原子配位。Cd(II)原子通过羧酸盐基团相连，形成一个异三核Cu(II)-Cd(II)-Cu(II)体系。Cd(II)原子以五角双锥几何构型七配位，有来自两个羧酸盐基团的四个O原子和三个水配体。异三核分子通过O-H⋯O氢键与未配位的水分子相连，形成三维骨架。
