(a) Scatter plot of ζ1 − ζ2 versus ϕ1 − ϕ2 with Ch1 = Ch2 = S and Ch3 = O/S/Se [Figs. 7[link](b) and 7[link](d)] (no fragments were observed with Ch3 = Te), see text for colour code. Frequency plots of geometrical angles: (b) ζ1A/1B = ∠C2A/2B—S2⋯Ch3 defined in Fig. 7[link](d) for the whole set of 513 motifs, (c) ζ1A/1B = ∠C2A/2B—S2⋯Ch3 defined in Fig. 7[link](d) for the 210 motifs showing Ch1⋯Ch2 ChB interactions, (d) ζ2A = ∠C1B—Ch3⋯S2 (Ch3 = O/S/Se) defined in Fig. 7[link](d) with Ch3 = O (yellow), Ch3 = S (orange) and Ch3 = Se (red) (no fragments were observed with Ch3 = Te).
