Crystal structures of three newly synthesized flavanone hydrazones.

ABSTRACT: The crystal structures of racemic mixtures of three new flavanone-hydrazones in the centrosymmetric space group (P ), are reported. The structures of (±,E)-N'-[5,7-dihy-droxy-2-(4-hy-droxy-phen-yl)chroman-4-yl-idene]-2-(naphthalen-1-yl)acetohydrazide ethyl acetate monosolvate, C₂₇H₂₂N₂O₅·C₄H₈O₂, and of (±,E)-N'-[5,7-dihy-droxy-2-(4-hy-droxy-phen-yl)chroman-4-yl-idene]-4-hy-droxy-benzo-hydra-zide ethanol monosolvate, C₂₂H₁₈N₂O₆·C₂H₅OH, both exhibit an intra-molecular O-H⋯N and multiple inter-molecular O-H⋯O and C-H⋯O-type hydro-gen bonds. The third structure, that of (±,E)-N'-(6-methoxy-2-phenyl-chroma
