Abstract : Cadmium(II) complexes, catena-poly[bis(thiocyanato-kappa N) bis(N-methylthiourea) cadmium(II)], [Cd(Metu)(2)(NCS)(2)](n) (1) and dicyanidobis(Nmethylthiourea) cadmium(II), [Cd(Metu)(2)(NCS)(2)] (2) were prepared and their structures were determined by single crystal X-ray analysis. In 1, the cadmium(II) ion is bound to four sulfur atoms of bridging Metu ligands and two nitrogen atoms of thiocyanate adopting a distorted octahedral environment. In 2, the geometry around cadmium is distorted tetrahedral attained by two cyanide ions and two methylthiourea molecules bound through the sulfur atoms. The crystal structures of both complexes show intra and intermolecular hydrogen bonding interactions. The complexes were also characterized by IR and NMR spectroscopy and the spectroscopic data were discussed in terms of the nature of bonding. [GRAPHICS] .
