S–H/π interactions in the CSD, based on a search for C/Si–S–H...Cπ distances ≤ 2.90 Å. Selected structures are shown, with the CSD code indicated. Minimum Hthiol–Caromatic distances are 2.48 Å (HOMPOP)42, 2.20 Å (WANCIX)43, 2.47 Å and 2.70 Å (ODOSAD)44, 2.49 Å (COLDEN)45, 2.79 Å (SIZBAE)46, and 2.78 Å (TAXMUA)10a. The distances for each structure are based on the hydrogen positions in the crystal structure CIF files, whose hydrogens for these examples are explicitly described in the original publications. The minimum Hthiol–Caromatic distances after standardization of S–H bond lengths to 1.338 Å are 2.33 Å, 2.15 Å, 2.45 Å, 2.62 Å, 2.54 Å, 2.94 Å, and 2.81 Å, respectively.
