Аннотация
A Schiff base, 4-hydroxy-6-methyl-3-[(1E)-1-(2-phenylhydrazinylidene)ethyl]-2H-pyran-2-one, is synthesized and characterized by 1H and 13C NMR, IR spectroscopy, ESI-mass spectrometry and single crystal X-ray diffraction analysis. There are three crystallographically independent molecules in the asymmetric unit, space group C2/c, a = 30.011(2) Å, b = 17.601(2) Å, c = 13.6878(13) Å, β = 92.532(4)°, and Z = 24. The final reliable index is 0.0406 for 5997 reflections. The molecules are linked through intermolecular N-H…O hydrogen bonds into three-linked molecules forming a supramolecular ring.
