(a) Scatter plot of ζ1 − ζ2 versus ϕ1 − ϕ2 with Ch1 = Ch2 = S and X = F/Cl/Br/I [Figs. 7[link](a) and 7[link](c)], see text for colour code. Frequency plots of geometrical angles: (b) ζ1A/1B = ∠C2A/2B—S2⋯X defined in Fig. 7[link](c) for the whole set of 219 motifs, (c) ζ1A/1B = ∠C2A/2B—S2⋯X defined in Fig. 7[link](c) for the 77 motifs showing Ch1⋯Ch2 ChB interactions, (d) ζ2A = ∠C1B—X⋯S2 (X = F/Cl/Br/I) defined in Fig. 7[link](c) with X = F (yellow), X = Cl (orange), X = Br (red) and X = I (purple).
