2-Amino-4-(4-methoxyphenyl)-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile
Abstract
The title compound, C17H16N2O3, crystallizes with two independent molecules in the asymmetric unit. In both molecules, the fused cyclohexenone ring adopts a sofa conformation. In the crystal, N—H...N and N—H...O hydrogen bonds link the molecules into corrugated layers parallel to the (101) plane.
