In the title orthorhombic polymorph (space group Iba2), C17H13N, the dihedral angle between the benzene rings is 55.99 (10)° and the azepine ring adopts a boat conformation. In the crystal, molecules are linked by C—H
π contacts. The previously-reported polymorph [Yousuf et al. (2012). Acta Cryst. E68, o1101] crystallizes in the monoclinic system (space group P21/c) with two molecules in the asymmetric unit.

In the title compound, C23H15F3N2O2S, the thiazole ring makes dihedral angles of 12.98 (13), 49.30 (11) and 49.83 (12)° with the pyridine ring, the methoxyphenyl ring and the (trifluoromethyl)phenyl ring, respectively. In the crystal, molecules are connected via C—HO hydrogen bonds, forming chains along [010]. There are also C—Hπ and C—Fπ interactions present, forming a three-dimensional structure.
