2-Amino-4-(4-methyl-phen-yl)-5-oxo-5,6,7,8-tetra-hydro-4H-chromene-3-carbonitrile.
The 4H-pyran ring of the title compound, C(17)H(16)N(2)O(2), is nearly planar [maximum deviation = 0.077 (2) Å] and the cyclo-hexene ring adopts a flattened chair conformation [puckering parameters: Q(T) = 0.435 (2) Å, θ = 122.0 (3)° and ϕ = 53.5 (3)°]. The 4H-pyran ring is almost perpendicular to the benzene ring [dihedral angle = 87.23 (8)°] and is almost coplanar with the mean plane of the cyclo-hexene ring [dihedral angle = 8.01 (8)°]. In the crystal, inversion-related mol-ecules are linked by pairs of inter-molecular N-H⋯N hydrogen bonds, forming inversion dimers with R(2) (2)(12) ring motifs. These dimers are further connected by N-H⋯O and C-H⋯N hydrogen bonds, forming a layer structure extending parallel to (0-12). Mol-ecules within the layers inter-act with each other via C-H⋯π inter-actions.
