2-(Biphenyl-4-yl)-5-[3-(4,5,6,7-tetra-hydrothieno[3,2-c] pyridine-5-ylsulfonyl)thiophen-2-yl]-1,3,4-oxadiazole

Abstract

In the title mol-ecule, C 25H 19N 3O 3S 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 tetrahydro-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.
