catena-Poly[[[(acetato-κ2 O,O′)cadmium]-μ-acetato-κ3 O,O′:O′-μ-{1,2-bisÂ[4-(pyridin-3-yl)pyrimidin-2-ylsulfanÂyl]ethane}-κ2 N 4,N 4′] trihydrate]
The title compound, {[Cd(CH3COO)2(C20H16N6S2)]·3H2O}n, exists as a one-dimensional zigzag polymer in which the CdII ion shows a seven-coordinate [CdO5N2] distorted pentaÂgonal–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-bisÂ[4-(pyridin-3-yl)pyrimidin-2-ylsulfanÂyl]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 π–π stacking interÂactions 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 molÂecules and the ligands
TriaquaÂchlorido[3-dimethylÂamino-1-(2-pyridÂyl)prop-2-en-1-one-κN 1]manganese(II) chloride
In the title compound, [MnCl(C10H12N2O)(H2O)3]Cl, the MnII ion has a distorted octaÂhedral coordination environment formed by one N and one O atom from the chelating 3-dimethylÂamino-1-(2-pyridÂyl)prop-2-en-1-one ligand, one chloride anion and three coordinated water molÂecules. InterÂmolecular O—H⋯O and O—H⋯Cl hydrogen bonds link the cations and anions into layers parallel to the ac plane
DiaquaÂdibromidobis[3-dimethylÂamino-1-(4-pyridyl-κN)prop-2-en-1-one]cadmium(II)
In the title compound, [CdBr2(C10H12N2O)2(H2O)2], the CdII ion is located on an inversion center and is six-coordinated by two N atoms [Cd—N = 2.377 (3) Å] from two different 3-dimethylÂamino-1-(4-pyridÂyl)prop-2-en-1-one ligands, two O atoms [Cd—O = 2.355 (2) Å] from two coordinated water molÂecules and two bromide anions [Cd—Br = 2.6855 (5) Å]. InterÂmolecular O—H⋯O hydrogen bonds link the molÂecules into layers parallel to the bc plane
