Selenium Sulfides, HPLC, Raman Spectra, 77Se NMR Spectra, X-RaySe5S in CS2 solution at 20 deg C spontaneously decomposes to give a mixture of 8 selenium-rich cyclic molecules which have been identified by reversed-phase HPLC and 77Se NMR spectroscopy as Se6, Se7, Se8, Se6S, Se7S, 1,2-Se6S2, 1,5-Se6S2, and 1,4-Se4S2.NMR spectra of Se5S, Se7S, and 1,5-Se6S2 have been measured for the first time; Raman spectra of solid Se5S and Se7S as well as crystal data of Se7S are reported in addition.A mechanism based on nucleophilic attack on Se5S is proposed for the formation of the products.
