(11-Methylpyrido[2,3-b][1,4]benzodiazepin-6-yl)(phenyl)methanone

Abstract

In the title compound, C20H15N3O, the diazepine ring adopts a boat conformation. The dihedral angle between pyridine and benzene rings is 55.2 (1)°. The benzoyl phenyl ring forms dihedral angles of 49.4 (1) and 75.9 (1)°, respectively, with the pyridine and benzene rings. In the crystal, mol­ecules are linked into centrosymmetric dimers by pairs of C—H⋯N hydrogen bonds.
