Crystal structure of 2-meth­oxy-2-[(4-meth­oxy­phen­yl)sulfan­yl]-1-phenyl­ethanone

In the title β-thio­carbonyl compound, C(16)H(16)O(3)S, the adjacent meth­oxy and carbonyl O atoms are synperiplanar [the O—C—C—O torsion angle is 19.8 (4)°] and are separated by 2.582 (3) Å. The dihedral angle between the rings is 40.11 (16)°, and the meth­oxy group is coplanar with the benzene ring to which it is connected [the C—C—O—C torsion angle is 179.1 (3)°]. The most notable feature of the crystal packing is the formation of methine and methyl C—H⋯O(carbon­yl) inter­actions that lead to a supra­molecular chain with a zigzag topology along the c axis. Chains pack with no specific inter­molecular inter­actions between them.
