Crystal structure of (E)-4-hy-droxy-6-methyl-3-{1-[2-(4-nitro-phen-yl)hydrazinyl-idene]eth-yl}-2H-pyran-2-one.

ABSTRACT: The title compound, C₁₄H₁₃N₃O₅ (HMNP), was synthesized by the simple condensation of p-nitro-phenyl-hydrazine with de-hydro-acetic acid (DHA) in a 1:1 molar ratio in ethanol. HMNP has been characterized by using FT-IR, ¹H and ¹³C NMR and UV-Vis spectroscopic and single-crystal X-ray diffraction techniques. The crystal packing reveals strong hydrogen bonds between the NH group and the carbonyl O atom of di-hydro-pyran-one moiety, forming chains along [101]. The thermal stability of the synthesized compound was confirmed by thermogravimetric analysis and it was found to be stable up to 513 K. The UV-Vis spectrum shows the presence of a strong band at λ_max 394 nm. ¹H NMR and single-crystal X-ray ana
