2-[(4-Chlorophenyl)sulfanyl]-2-methoxy-1-phenylethan-1-one: Crystal structure and Hirshfeld surface analysis

Abstract

The title compound, C15 H13 ClO2 S, comprises (4-chlorophenyl)sulfanyl, benzaldehyde and methoxy residues linked at a chiral methine-C atom (the crystal is racemic). A twist in the methine-C - C(carbonyl) bond [O - C - C - O torsion angle = 19.3 (7)°] leads to a dihedral angle of 22.2 (5)°between the benzaldehyde and methine+methoxy residues. The chlorobenzene ring is folded to lie over the O atoms, with the dihedral angle between the benzene rings being 42.9 (2)°. In the crystal, the carbonyl-O atom accepts two C - H...O interactions with methyl- and methine-C - H atoms being the donors. The result is an helical supramolecular chain aligned along the c axis; chains pack with no directional interactions between them. An analysis of the Hirshfeld surface points to the important contributions of weak H...H and C...C contacts to the molecular packing.
