    • Atomic charges for crystal structures of 1, 2, and corresponding sulfur analogues (15-UT-5 and 18-UT-6) were calculated by using B3LYP with the LANL2DZ basis set. The calculated atomic charges (averages) are as follows. For 1: C, -0.439; H, 0.301; Se, 0.277. For 2: C, -0.450; H, 0.305; Se, 0.290. For 15-UT-5: C, -0.393; H, 0.259; S, 0.269. For 18-UT-6: C, -0.429; H, 0.301; S, 0.257.
