A vibrational study of the (S–S) group in transition-element compounds
Abstract
The i.r. spectra of polysulphides MS3(M = Ti, Zr, Nb, and U), VS4, and thiohalides NbS2X2(X = Cl, Br, and I) and the Raman spectra of the latter were investigated to determine the vibrational range of their (S–S) group as distinguishable from pyrites-type (S–S) groups: we show the existence of such groups in Mo2S5Cl3 and Mo2S5Br3.
