| Abstract: | The spectral characterization of cadmium(II) complexes of the general formula [Cd(Tmtu)2X2] (Tmtu = tetramethylthiourea, X = Cl?, Br?, I?, and SCN?) as well as the X-ray structure of one of them, [Cd(Tmtu)2Cl2] (I) is described. In (I), the cadmium atom lies on a twofold rotation axis and has a distorted tetrahedral coordination environment defined by two S atoms of telramelhylthioures (Tmtu) ligands and two chloride ions. The crystal structure is stabilized by non-classical intramolecular C-H?N and C-H?S hydrogen bonding interactions involving the methyl H and sulfur or nitrogen atoms. The spectroscopic data were discussed in terms of the nature of bonding. |
