title: Crystal structure of 2-oxo-N'-phenyl-2H-chromene-3-carbohydrazide.
abstract: 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 intra-molecular 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 mol-ecules, forming [100] chains.
