3-Amino-1-phenyl-1H-benzo[f]chromene-2-carbonitrile

Abstract

In the title compound, C20H14N2O, the phenyl ring is almost normal to the naphthalene ring system with a dihedral angle of 86.72 (9)°. The 4H-pyran ring fused with the naphthalene ring system has a boat conformation. In the crystal, molecules are linked into a helical supramolecular chain along the b axis via N—H...N hydrogen bonds. The chains are consolidated into a three-dimensional architecture by C—H...π interactions.
