Abstract

The analysis of gas electron diffraction data yielded the bond lengths (rg) of diphenyl sulphone, (C6H5)2SO2: CC 1.400(3) Å, CH 1.100(11) Å, SC 1.772(5) Å and SO 1.440(5) Å, and of diphenyl sulphoxide, (C6H5)2 SO: CC 1.398(3) Å, CH 1.105(11) Å, SC 1.804(6) Å and SO 1.489(5) Å. Limited information on the bond angles and conformation was obtained. The data on the stretching frequencies and lengths of SO bonds for sulphoxides are consistent with the relationship established for sulphones between [0.5 (ν2 s + ν2 as)]0.5 and r(SO).
