Crystal structure of diaqua(μ2-triethylenetetraminehexaacetato)dizinc tetrahydrate
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 sur...
