Two independent molecules (A and B) comprises the asymmetric unit of the title ester, C17H20OS. The phenyl ring is inclined with respect to the thiocarboxyl group, forming dihedral angles of 58.95 (6) (in molecule A) and 62.28 (6)° (in molecule B). In each independent molecule, one adamantyl methylene C atom is nearly coplanar with the thiocarboxyl group. The major difference between molecules A and B relates to the relationship between the S atom and the coplanar adamantyl methylene C atom [Ca—Cq—Cc—S torsion angles = 178.25 (8) and 6.81 (13)°, respectively; Ca = adamantyl methylene C atom, Cq = quaternary C atom and Cc = carbonyl C atom], whereby the S atom in molecule A has an anti relationship with the methylene C atom and in molecule B, the S atom is syn. In the crystal, C—H...π interactions are formed leading to supramolecular layers in the ac plane.
