1,6,6aλ-Trithiapentalene and 1,6-dioxa-6aλ-thiapentalene have, by means of H n.m.r. spectroscopy in a nematic phase, been shown to possess symmetry in solution. Quantitative structural parameters have been obtained for both compounds. A detailed structure of 1,6-dioxa-6aλ-thiapentalene has been obtained by combina
