Item 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(2011) Fun, H.-K.; Hemamalini, M.; Rai, S.; Isloor, A.M.; Shetty, P.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.Item 2-(5-Bromopyridin-3-yl)-5-[3-(4,5,6,7-tetrahydrothieno[3,2-c] pyridine-5-ylsulfon-yl)thio-phen-2-yl]-1,3,4-oxa-diazole(2011) Fun, H.-K.; Hemamalini, M.; Rai, S.; Isloor, A.M.; Shetty, P.In the title compound, C 18H 13BrN 4O 3S 3, the tetra-hydro-pyridine ring adopts a half-chair conformation with the central methylene-C atom of the NCH 2CH 2 unit at the flap. The dihedral angles between the tetra-hydro-pyridine ring and the pyridine and two thiophene rings are 69.34 (13) 5.66 (13) and 68.63 (13)°, respectively, while the dihedral angle between the 1,3,4-oxadiazole and tetrahydropyridine rings is 54.76 (13)°. The molecule is stabilized by an intramolecular C-H?N interaction. In the crystal, adjacent molecules are connected via bifurcated C-H?(N,O) hydrogen bonds, forming a chain along the b axis.
