Abstract

In the title moleclue, C(16)H(13)ClN(2)O(2), the cyclo-hexene ring is in a sofa conformation. The pyran ring is essentialy planar [maximum deviation = 0.038 (2) Å] and forms a dihedral angle of 89.68 (10)° with the benzene ring. In the crystal, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds, forming inversion dimers with R(2) (2)(12) ring motifs. These dimers are further linked by N-H⋯O hydrogen bonds into chains along [110]. Weak C-H⋯O hydrogen bonds are also present.
