(3E)-4-[(Naphthalen-1-yl)amino]-pent-3-en-2-one hemihydrate.

The title compound, C15H15NO·0.5H2O, was prepared from α-naphthyl-amine and 2,4-penta-nedione in a 1:1 ratio. An intra-molecular N-H⋯O hydrogen bond in the N-naphthyl-pent-3-en-2-one mol-ecule involving the amine and carbonyl groups strengthens the structure. The water mol-ecule interacts with two symmetry-related N-naphthyl-pent-3-en-2-one mol-ecules viaby O-H⋯O hydrogen bonds.

The synthesis and characterization of poly[di-chlorido-tri(1,3-thia-zolidine-2-thione)cadmium(II)], [CdCl2(C3H5NS2)3] n , prepared from CdCl2·H2O and C3H5NS2 (tzdSH) in a 1:3 ratio, are described. The CdII cation is coordinated by three 1,3-thia-zolidine-2-thione mol-ecules and three Cl- anions in a distorted octa-hedral environment. The Cd metal centres are connected via Cl- ligands, creating polymeric chains running along the a-axis direction. The conformation of the chains is stabilized by N-H⋯Cl hydrogen bonds.
