چکیده
In the title mol-ecule, C(25)H(19)N(3)O(3)S(3), the tetra-hydro-pyridine ring adopts a half-chair conformation. The dihedral angle between the least-squares plane through the tetra-hydro-pyridine ring and two thio-phene and two benzene rings are 6.25 (9), 89.49 (9), 76.43 (9) and 84.93 (8)°, respectively, while the dihedral angle between the 1,3,4-oxadiazole and tetra-hydro-pyridine rings is 81.14 (9)°. In the crystal, adjacent mol-ecules are connected via weak C-H⋯N hydrogen bonds, forming a chain along the b axis.
