Abstract
The structures of the highly substituted title heterocycles, C20H22N2S and C20H22N2O2S, have been determined at 123 (1) K. Both molecules possess exact C-2 symmetry and the seven- membered rings have very similar twist-boat conformations. The magnitudes of the C-S-C bond angles, 107.13 (6) and 108.27 (7)degrees, respectively, are influenced significantly by the four substituent methyl groups on the seven-membered rings.
