Abstract
In the title compound, C20H13N3S, the partially saturated ring adopts a twisted half-boat conformation with the methylene C atom closest to the aminobenzene ring lying 0.690 (6) Å out of the plane defined by the five remaining atoms. The dihydrophenanthrene residue has a folded conformation [dihedral angle between the outer benzene rings = 26.27 (18)°]. The thiophen-2-yl ring forms a dihedral angle of 63.76 (19)° with the benzene ring to which it is attached. In the crystal, inversion dimers linked by pairs of N—H⋯N hydrogen bonds generate R 2 2(12) loops. The dimers are linked into layers in the bc plane by weak C—H⋯π interactions. The thiophen-2-yl ring is disordered over two essentially coplanar but opposite orientations in a 0.918 (4):0.082 (4) ratio.
