2-Amino-4-(2-chlorophenyl)-5,10-dioxo-5,10-dihydro-4H-benzo[g]chromene-3-carbonitrile
In the molecule of the title compound, C20H11ClN2O3, the pyran ring adopts a flattened-boat conformation. In the crystal structure, intermolecular N—H...N and N—H...O hydrogen bonds generate edge-fused R22(12) and R22(14) ring motifs; the hydrogen-bonded motifs are linked to each...
