ABSTRACT
Four independent molecules comprise the asymmetric unit of the title compound, C17H14N2O2. The central pyrazoline ring is flanked by an N-bound benzene ring and a C-bound methoxy-substituted benzene ring. The greatest difference between the independent molecules is found in the relative orientations of the benzene rings with the range of dihedral angles being 23.59 (6)–42.55 (6)°. In the crystal, extensive C—H...O interactions link molecules into layers parallel to (02overline{1}) and these are linked by C—H...π contacts.
