Özet

In the title moleclue, C16H13ClN2O2, the cyclohexene ring is in a sofa conformation. The pyran ring is essentialy planar [maximum deviation = 0.038 (2) angstrom] and forms a dihedral angle of 89.68 (10)degrees with the benzene ring. In the crystal, molecules are linked by pairs of N-H center dot center dot center dot N hydrogen bonds, forming inversion dimers with R-2(2)(12) ring motifs. These dimers are further linked by N-H center dot center dot center dot O hydrogen bonds into chains along [110]. Weak C-H center dot center dot center dot O hydrogen bonds are also present.
