S 4 (CN) 2 crystallizes in the monoclinic space group P2 1 /c with a = 885.7 pm, b = 794.2 pm, c = 1032.6 pm, β = 109.0° (at 173 K). The molecules occupy general sites but are of approximate C 2 symmetry. The conformation of the molecules is all‐trans with torsional angles CSSS = 74.6° and 81.7° and SSSS = 84.8°. The central SS bond (201.7 pm) is much shorter than the terminal SS bonds (av. 206.8 pm). There are no stronger than van‐der‐Waals type intermolecular interactions.
