Part of the crystal structure of (I)

, showing the formation of a ribbon of edge-fused rings built from two independent C—H⋯π(arene) hydrogen bonds (dashed lines). For the sake of clarity, H atoms not involved in the motifs shown have been omitted. The S atoms marked with an asterisk (*), a hash (#) or a dollar sign ($) are at the symmetry positions (x, y + 1, z), (x, y − 1, z) and (−x + $[{1\over 2}]$ , y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ), respectively.
