Abstract
Titanocene pentasulfide reacts with sulfuryl chloride under suitable conditions to give a mixture of mainly S10, S15, and S20 which can be separated by repeated crystallization and precipitation. Pure S15 is obtained as a lemon-yellow powder at low temperatures which transforms to a sticky mass at 20 °C. Solutions of S15 in CS2 are stable at 20 °C for months. Pure S15 does not decompose at 20 °C within a few hours. Raman spectra of S15 show stretching vibrations at 409-480 cm-1 and bending and torsional modes at < 270 cm-1.Keywords
