Abstract The structures of the title compounds4 and5 have been determined by single crystal X-ray methods. Both molecules contain the approximately planar C4N2S2 group with 10 π-electrons which are mainly delocalized. The mean C—C bond distances in the four membered ring system are 146.1 (4) for4 and 143.8 (7) pm for5, with small individual variations either. In both molecules the C—S and C—N bond distances are 165 and 132 pm, respectively.4 has a crystallographic two fold axes,5 an inversion center. The packing mode of both molecules is very similar.
