(Adamantan-1-yl)(phenyl­sulfan­yl)methanone

Two independent mol­ecules (A and B) comprises the asymmetric unit of the title ester, C(17)H(20)OS. 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 [C(a)—C(q)—C(c)—S torsion angles = 178.25 (8) and 6.81 (13)°, respectively; C(a) = adamantyl methyl­ene C atom, C(q) = quaternary C atom and C(c) = 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.
