3,4,5-Trimethyl-2,4,6-triphenyl-4H-thio­pyran

Rahmani H, Pirelahi H, Ng SW - Acta Crystallogr Sect E Struct Rep Online (2009)

Bottom Line: The six-membered thio-pyran ring in the title compound, C(26)H(24)S, adopts a boat conformation, with the S atom displaced by 0.478 (2) Å and the 3-methyl-ene C atom by 0.644 (2) Å from the plane of the other four sp(2)-hydridized C atoms.The methyl group on the methyl-ene carbon lies in a pseudo-equatorial position and the phenyl ring in a pseudo-axial position.
