Triaqua-bis{μ-N-[N-(4-meth-oxy-2-oxidobenzyl-idene)glyc-yl]glycinato(3-)}cadmium(II)dicopper(II) dihydrate.

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.
