title: Hexaaqua-magnesium(II) bis-{[N-(4-meth-oxy-2-oxidobenzyl-idene)glycyl-glycinato(3-)]cuprate(II)} hexa-hydrate.
abstract: In the title complex, [Mg(H(2)O)(6)][Cu(C(12)H(11)N(2)O(5))](2)·6H(2)O, the Cu(II) atoms lie at the center of the square plane of triple negatively charged O,N,N',O'-tetra-dentate Schiff base ligands, which are coordinated by one phenolate O atom, one imine N atom, one deprotonated amide N atom and one carboxyl-ate O atom. The Mg(II) center, which sits on an inversion center, is coordinated by six aqua ligands and exhibits a slightly distorted octa-hedral conformation. The asymmetric unit consists of an [N-(4-meth-oxy-2-oxidobenzyl-idene)glycyl-glycinato]cuprate(II) anion, one half of an [Mg(H(2)O)(6)](2+) cation and three free water mol-ecules. The cations and anions form columns by O-H⋯O hydrogen bonds.
