Notes:
The structures of the highly substituted title heterocycles, C20H22N2S and C20H22N2O2S, have been determined at 123 (1) K. Both molecules possess exact C2 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)°, respectively, are influenced significantly by the four substituent methyl groups on the seven-membered rings.
