The tetracarboxylatobenzene tetraanion in μ-(1,2,4,5-benzenetetracarboxylato-O1:O4)bis[aqua(4-azaheptane-1,7-diamine-N, N′, N′′) copper(II)] octahydrate, [{Cu(C6H17N3)(H2O)}2(μ-C10H2O8].8H2O, bridges two N′N′′N′′′-chelated aquacopper entities in a monodentate manner to give rise to square-pyramidal coordination at the metal centres. Hydrogen bonding involving the three nitrogen atoms, the four carboxyl O atoms and the five water molecules gives rise to a three-dimensional network structure.
