Abstract
Complexes of thiomorpholin-3-one, thiomorpholin-3-thione, thiazolidine-2-thione, and thiazolidine-2-selenone with CrX3•nH2O (X = Cl, Br, I) were prepared and characterized. On the basis of vibrational (conventional and far infrared) and electronic spectroscopy, magnetism and conductivity measurements, the structures of these complexes were identified. The bonding occurs through the oxygen in the complexes of thiomorpholin-3-one and through the nitrogen in all the remaining complexes. The complexes crL3x3 involve unidentate ligands, are neutral, monomeric, and hexacoordinate. Spectroscopic parameters for the complexes have been calculated and compared with similar chromophores containing CrN3X3, CrO3X3, and CrS3X3 chromophores.Keywords
