چکیده
The reaction of ZnO and tri-ethyl-ene-tetra-minehexaacetic 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] mol-ecule in the crystalline state. Both Zn(II) ions are octahedrally surrounded and bound by an N2O3 donor set from the H2TTHA(4-) anion and a water mol-ecule; the N atoms are cis and the water mol-ecule is trans to an N atom. The Zn⋯Zn separation is 7.562 (1) Å. An intra-molecular C-H⋯O inter-action is observed and both carboxyl-ate 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.

In the title compound, {[Zn(C(4)H(4)O(6))(H(2)O)]·2H(2)O}(n), the l-tartrate ligands adopt μ(4)- and μ(2)-coordination modes. The Zn(II) atom adopts an octa-hedral geometry and is chelated by two kinds of l-tartrate ligands through the hydr-oxy and carboxyl-ate groups and coordinated by one unchelating carboxyl-ate O atom and one water mol-ecule. In the crystal, the l-tartrate ligands link the ...
