Abstract
Abstract Coordination compounds of ethylene trithiocarbonate (ETTC) with some Zn(II), Cd(II) and Hg(II) halides have been prepared, characterized and their infrared and Raman spectra recorded. The i.r. spectra in the range 4000-400 cm −1 suggest that the organic ligand is bonded to the metal ions through its exocyclic sulphur atom, whereas the far-i.r. and Raman spectra show that the complexes of the type HgX 2 (ETTC) (X = Cl, Br or I) possess a trans dimeric halogen-bridged structure. The Cd(II) and Zn(II) species are of the type MX 2 (ETTC) 2 and they possess a pseudotetrahedral structure of C 2υ symmetry.
