Abstract

Low temperature X-ray structural analyses of monoclinic single crystals of S10 and S6 · Si10 (prepared from the components) show that the cyclic S10 molecule exhibits the same D2 conformation in both compounds with bond distances between 203.3 and 208.0 pm, bond angles (α) between 103 and 111°, and torsional angles (τ) between 73 and 124°. The S6 molecule (site symmetry Ci) in S6 · S10 is very similar to the one in pure S6 (dSS = 206.2 pm, α= 103°, τ = 74°). All intermolecular interactions are of van-der-Waals type. The Raman spectrum of S6 · S10 can be explained by a superposition of the S6 and S10 spectra
