چکیده
The six-membered thio-pyran ring in the title compound, C(24)H(20)S, adopts a flattened boat conformation, with the S atom displaced by 0.273 (2) Å and the 3-methyl-ene C atom by 0.294 (3) Å from the plane of the other four sp(2)-hydridized C atoms. The methyl group on the methyl-ene carbon lies in a axial position with the phenyl equatorial.
