Abstract
The six-membered thiopyran ring in the title compound, C26H24S, adopts a boat conformation, with the S atom displaced by 0.478 (2) Å and the 3-methylene C atom by 0.644 (2) Å from the plane of the other four sp 2-hydridized C atoms. The methyl group on the methylene carbon lies in a pseudo-equatorial position and the phenyl ring in a pseudo-axial position.

Experimental 4-Methyl-2,4,6-triphenyl-4H-thiopyran was was synthesized by the reaction of methyl magnesium bromide and 3,5-dimethyl-2,4,6triphenyl thiopyrylium perchlorate in dry ether under an argon atmosphere according to a reported method (Rahmani & Pirelahi, 1997)
