Abstract

Complexes of the type SnCl4·2L, TiCL4·2L and FeX2·2L [X = Cl, Br, I; L = 2-thiazolidinethione (tzt), 2,4-thiazolidinedione (tzd), ethylene monothiocarbonate (emt)] have been prepared and characterized by elemental analysis, infrared spectra, magnetic moment and conductance measurements. The infrared spectral results indicate that in tzt the amino nitrogen and in tzd and emt the carbonyl oxygen are the donor sites. The group theoretical calculations show that SnCl4 and TiCl4 complexes are trans octahedral. The magnetic moment values show that all iron complexes are tetrahedral.
