Catena-Poly[[[(acetato-?O,O')cadmium]-?-acetato-?O,O':O'-?-{1,2-bis-[4-(pyridin-3-yl)pyrimidin-2-ylsulfan-yl]ethane}-?N,N] trihydrate].

ABSTRACT: The title compound, {[Cd(CH(3)COO)(2)(C(20)H(16)N(6)S(2))]·3H(2)O}(n), exists as a one-dimensional zigzag polymer in which the Cd(II) ion shows a seven-coordinate [CdO(5)N(2)] distorted penta-gonal-bipyramidal geometry with the N atoms in axial positions and an N-Cd-N angle of 176.94?(13)°. The metal atoms are bridged by 1,2-bis-[4-(pyridin-3-yl)pyrimidin-2-ylsulfan-yl]ethane ligands, giving a polymeric chain extending along the b axis. Adjacent chains related by an inversion center are further bridged by Cd-O bonds formed between the O atom of one of the acetate ligands and the metal atom. The five Cd-O bond lengths are in the range 2.329?(3)-2.485?(3)?Å. There are ?-? stacking inter-actions between the aromatic rings of adjacent polymeric chains, the centroid-centroid distances being 3.556?(3) and 3.698?(3)?Å, organizing the chains into a three-dimensional framework. This framework is additionally stabilized by extensive O-H?O and O-H?N hydrogen bonding between water mol-ecules and the ligands.
