Abstract
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.
