The reaction of ZnO and triethylenetetraminehexaacetic acid (H6TTHA) in aqueous solution after refluxing yields the binuclear title compound, [Zn2(C18H26N4O12)(H2O)2]·4H2O. There is a centre of symmetry in the [Zn2(H2TTHA)(H2O)2] molecule in the crystalline state. Both ZnII ions are octahedrally surrounded and bound by an N2O3 donor set from the H2TTHA4- anion and a water molecule; the N atoms are cis and the water molecule is trans to an N atom. The Zn⋯Zn separation is 7.562 (1) Å. An intramolecular C - H⋯O interaction is observed and both carboxylate H atoms are disordered over two adjacent sites. In the crystal, the components are linked by O - H⋯O and C - H⋯O hydrogen bonds generating a three-dimensonal network.
