Description
Summary:In the title β-thiocarbonyl compound, C16H16O3S, 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.
