“…The X-ray data of 1a shows that the molecule (Figure 2) is essentially planar, with maximum deviation being 0.026 Å (C6) and, although the S-S separation is so far the longest found [11], the geometric parameters (Table 2) follow the structural pattern that characterizes the 1,2-dithiole-3-thiones, viz. bond distances: S-S, 2.047-2.050 Å ; CסS, 1.655-1.669 Å ; and C-S, 1.731-1.762 Å , with the endocyclic angle subtended at S2 being larger than the one at S1.…”
