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.
