Crystal structure of 2-methoxy-2-[(4-methylphenyl)sulfanyl]-1-phenylethan-1-one

Abstract

In the title β-thiocarbonyl compound, C16H16O2S, the carbonyl and methoxy O atoms are approximately coplanar [O—C—C—O torsion angle = −18.2 (5)°] and syn to each other, and the tolyl ring is orientated to lie over them. The dihedral angle between the planes of the two rings is 44.03 (16)°. In the crystal, supramolecular chains are formed along the c axis mediated by C—H...O interactions involving methine and methyl H atoms as donors, with the carbonyl O atom accepting both bonds; these pack with no specific intermolecular interactions between them.
