ABSTRACT
The asymmetric unit of the title compound, C(18)H(11)NO(2)S, contains two crystallographically independent mol-ecules. In one mol-ecule, the oxazole and thio-phene rings are oriented at dihedral angles of 17.40â
(9) and 18.18â
(7)° with respect to the naphthalene ring system, while the oxazole and thio-phene rings are oriented to each other at a dihedral angle of 0.86â
(9)°. In the other mol-ecule, the corresponding angles are 3.05â
(8), 9.62â
(6) and 7.02â
(8)°, respectively. In each mol-ecule, a weak intra-molecular C-Hâ¯N hydrogen bond links the oxazole N atom to the naphthalene group. Weak inter-molecular C-Hâ¯O hydrogen bonding is present in the crystal structure. π-π stacking between the oxazole and thio-phene rings, between the thio-phene and naphthalene rings, and between the oxaozole and naphthalene rings, [centroid-centroid distances = 3.811â
(2), 3.889â
(2), 3.697â
(2) and 3.525â
(2)â
Å] may further stabilize the crystal structure.
