Frequency distributions in Ch⋯Ch (Ch = S/Se/Te) ChB interactions within homo-Ch3 synthons. For Ch = S, Se and Te, the Ch⋯Ch distance and the |Δζ| angular orientation are represented in (a) and (d), (b) and (e), and (c) and (f), respectively. The motif shown in Fig. 10[link](c) was used for the CSD search with the geometrical parameters d (Ch⋯Ch) ≤ sum(vdW) + 0.4 Å and ζ1 and ζ2 angles within the range 60–180°. vdW radii = 1.80, 1.90 and 2.06 Å for S, Se and Te atoms, respectively.
