A series of cadmium(II) complexes with N-alkyl or aryl and N,N′-dialkyl or diaryl thioureas (RNHCSNHR′; where R = R′ = CH3, CH2CH3, C6H5 and or R′ = H) have been synthesised and characterised. The structures of the polymer [CdCl2(CS(NH2) NHCH3)2]n (I) and monomer [CdCl2(CS(NH2)NHCH2CH)2] (II) were determined by single crystal X-ray methods. The structure (I) is a polymer chain built from [CdCl3S3] distorted octahedra. Complex II is monomeric with a distorted tetrahedral geometry at the cadmium centre. 1H NMR spectroscopy in deuterated dimethyl sulfoxide at room temperature had broadened NH peaks in the lower field (region 6.0-10.0 ppm) which indicates the presence of both cis and trans-isomers for the N-alkylthioureas. All the spectroscopic data obtained are consistent with the coordination of ligands by sulphur atom to the metal ion. Thermogravimetric studies show that several of these complexes decompose cleanly to CdS and may be useful in materials preparation.
