title: 2,6-Diphenyl-4-(2-thien-yl)-1,4-dihydro-pyridine-3,5-dicarbonitrile.
abstract: The asymmetric unit of the title compound, C(23)H(15)N(3)S, contains two crystallographically independent mol-ecules. The pyridine rings adopt envelope conformations. The thio-phene rings are oriented at dihedral angles of 77.97 (4)/53.53 (4) and 78.44 (4)/57.11 (4)° with respect to the phenyl rings, while the dihedral angles between the phenyl rings are 48.51 (4) and 44.49 (4)°. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains along the c axis. The S, C and H atoms of one of the thio-phene rings are disordered over two orientations, with occupancy ratios of 0.314 (15):0.686 (15).
