Abstract
In the title compound, C40H29N3O3S, the pyran ring adopts a sofa conformation, the thiazolidine ring adopts a twisted conformation and the pyrrolidine ring adopts an envelope conformation with the N atom as the flap. The pyrazole ring is essentially planar [maximum deviation = 0.002 (2) Å] and forms dihedral angles of 4.8 (1) and 39.0 (1)°, respectively, with the benzene rings attached to the N and C atoms. The acenapthylene ring system is approximately planar [maximum deviation = 0.058 (2) Å] and forms dihedral angles of 85.9 (1) and 48.5 (1)°, respectively, with the pyrollothiazole and chromene ring systems. The molecular conformation is stabilized by three weak intramolecular C—H⋯O hydrogen bonds, which generate one S(8) and two S(6) ring motifs. In the crystal, pairs of C—H⋯O hydrogen bonds link centrosymmetrically related molecules into dimers, generating R 2 2(14) ring motifs. The crystal packing also features pairs of C—H⋯π interactions, which link the dimers into a supramolecular chain along the b axis.
