title: A second modification of poly[diaquadi-μ-citrato(3-)-trizinc(II)].
abstract: A second modification of the zinc(II) coordination polymer with citric acid, [Zn(3)(C(6)H(5)O(7))(2)(H(2)O)(2)](n) or [Zn(citrate)(2)(H(2)O)(2)], has been synthesized under hydro-thermal conditions by reacting zinc acetate with citric acid. The structure contains two unique Zn atoms, one with a distorted octa-hedral coordination and located on an inversion centre, and one with a distorted tetra-hedral coordination. The ZnO(6) and ZnO(4) units are linked into layers extending parallel to (010).
