The crystal structure of the title compound has been determined from X-ray diffraciometer data and refined by least squares to R 0.035 (749 reflections). Crystals are monoclinic, P21/n, a = 7.812(1), b = 15.276(3), c = 6.271-(2) Å, β = 96.41(1)°, 2 = 4. The non-hydrogen atom geometry of the planar system has been corrected throughout for thermal motion ; the conjugation is extensive throughout the S·CS·N·CS·N part of the ring but not in the N-S bond. Considerable repulsion distorts the geometry of the peripheral sulphur and methyl groups.
