2,4-Diethylthioxanthen-9-one

The asymmetric unit of the title compound, C17H16OS, contains two crystallographically independent molecules, one of which is nearly planar, the outer rings making dihedral angles of 1.51 (3) and 1.09 (3)° with the central ring. In the crystal structure, weak intermolecular C—H...O hydrogen bonds link molecules into chains parallel to the a axis. π–π Contacts between the thioxanthone rings [centroid–centroid distances = 3.798 (3) and 3.781 (3) Å] may further stabilize the structure.
