title: Bis(4,4'-bipyrid-yl)bis{2-[4,6-bis-(carboxy-methyl-sulfan-yl)-1,3,5-triazin-2-ylsulfan-yl]acetato}zinc(II).
abstract: In the title compound, [Zn(C(9)H(8)N(3)O(6)S(3))(2)(C(10)H(8)N(2))(2)], the central Zn(II) ion, situated on a center of inversion, adopts an octa-hedral geometry coordinated by four O atoms from two carboxyl-ate groups and two carboxylic groups of two symmetry-related TTTA ligands and two N atoms from two bpy mol-ecules {TTTA is 2,2',2''-[1,3,5-triazine-2,4,6-triyltris(sulfanedi-yl)]triacetic acid and bpy is 4,4'-bipyridine}. These mononuclear units are connected through complementary O-H⋯X hydrogen bonds, as well as through weak C-H⋯X (X = O and N) inter-actions, resulting in a three-dimensional supra-molecular architecture.
