title: trans-mu-Oxamido-N,N'-diethanoato-bis[diaquacopper(II)] dihydrate.
abstract: The title complex, trans-(mu-2,2'-[(1,2-dioxoethane-1,2-diyl)diimino]diethanoato(4-))bis[diaquacopper(II)] dihydrate, [Cu2(C6H4N2O6)(H2O)4] x 2H2O, with a three-dimensional framework, displays a square-pyramidal coordination geometry. The structure consists of a neutral centrosymmetric binuclear unit in which the oxamide ligand has a trans geometry, is fully deprotonated and acts in a bis-tridentate fashion.
