Study of the Reactions of Chromium(III) Halides and Heterocyclic Ligands Containing Group VA and VIA Donor Atoms

Abstract

C. PRETI and G. TOSI. Can. J. Chem. 52,2845Chem. 52, (1974. Complexes of thiomorpholin-3-one, thiomorpholin-3-thione, thiazolidine-2-thione, and thiazolidine-2-selenone with CrX,,nH,O (X = C1, 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 CrL,X, involve unidentate ligands, are neutral, monomeric, and hexacoordinate. Spectroscopic parameters for the complexes have been calculated and compared with similar chromophores containing CrN3X,, Cr0,X3, and CrS3X3 chromophores.

“…In the spectrum of (IV) the band of ν(C=S,C=N) was appeared at 1477 cm -1 (Ram, 1963), the shifting of this band in (III) to 1483 cm -1 suggests the effect of withdrawing group (-CH 2 CH-Cl) on (N=C=S) band (Al-Hete, 1999). The shifting of ν(C=N) band in spectra of (III) at 713 cm -1 to two splited bands at (677-747) cm -1 in spectrum of ligand (IV) and compared it with deprotonated thiozolidine (Preti and Tosi, 1974).…”
