Despite the large atomic radii, the CS ⋅⋅⋅ Sb distances in (RCSS)2MR1 (M = As, Sb, Bi; R1 = aryl) and the CO ⋅⋅⋅ Sb distances in (RCOS)xMR (M = As, Sb, Bi; x = 2, 3) are comparable to or shorter than those of the corresponding arsenic derivatives (Tables 2 and 3). A molecular-orbital calculation performed on the model compounds (MeC(E)E1)3−xMMex (M = As, Sb, Bi; E = O, S; E1 = S, Se; x = 1, 2) at the
