title: 4-(4-Bromo-phen-yl)-3-methyl-1-phenyl-6,7-dihydro-1H-pyrazolo-[3,4-b]thieno[2,3-e]pyridine 5,5-dioxide.
abstract: In the title compound, C(21)H(16)BrN(3)O(2)S, the pyrazole and pyridine rings are nearly coplanar, the dihedral angle between their planes being 3.17 (14)°. The 2,3-dihydro-thio-phene ring adopts an envelope conformation. The 4-bromo-phen-yl/pyridine ring and phen-yl/pyrazole rings form dihedral angles of 60.06 (9) and 33.49 (11)°, respectively. There is an intra-molecular C-H⋯N hydrogen bond. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonding and C-H⋯π inter-actions.
