Crystal structure of 2-oxo-N′-phenyl-2H-chromene-3-carbohydrazide

In the title compound, C16H12N2O3, the 2H-chromene moiety is essentially planar, with an r.m.s. deviation of the nine constituent atoms from the mean plane of 0.0093 Å, and makes a dihedral angle of 76.84 (3)° with the pendant phenyl ring. An intramolecular N—H...O hydrogen bond helps to determine t...

Description
Summary:In the title compound, C16H12N2O3, the 2H-chromene moiety is essentially planar, with an r.m.s. deviation of the nine constituent atoms from the mean plane of 0.0093 Å, and makes a dihedral angle of 76.84 (3)° with the pendant phenyl ring. An intramolecular N—H...O hydrogen bond helps to determine the conformation of the side chain. In the crystal, N—H...O and N—H...N hydrogen bonds link the molecules, forming [100] chains.
