2-Amino-4-(4-meth-oxy-phen-yl)-5-oxo-5,6,7,8-tetra-hydro-4H-chromene-3-carbonitrile 1,4-dioxane hemisolvate.
In the crystal structure of the title compound, C(17)H(16)N(2)O(3)·0.5C(4)H(8)O(2), pairs of N-H⋯N hydrogen bonds link mol-ecules into dimers with R(2) (2)(12) motifs, which are connected by N-H⋯O hydrogen bonds, forming a supra-molecular array in the ab plane. The 1,4-dioxane ring, which lies about an inversion center, adopts a chair conformation.
