A second modification of poly[diaquadi--citrato(3-)-trizinc(II)]

X.-H. Li, W.-L. Chen and E.-B. Wang

Abstract: A second modification of the zinc(II) coordination polymer with citric acid, [Zn₃(C₆H₅O₇)₂(H₂O)₂]_n or [Zn(citrate)₂(H₂O)₂], has been synthesized under hydrothermal conditions by reacting zinc acetate with citric acid. The structure contains two unique Zn atoms, one with a distorted octahedral coordination and located on an inversion centre, and one with a distorted tetrahedral coordination. The ZnO₆ and ZnO₄ units are linked into layers extending parallel to (010).
