N-(4-Fluorobenzoyl)-2-hydroxy-4-methylbenzohydrazide
In the title compound, C(15)H(13)FN(2)O(3), the aromatic rings are aligned at an angle of 10.15 (3)°. The mol-ecules are packed with π-π stacking inter-actions [mean inter-planar distances of 3.339 (2) and 3.357 (3) Å] and the crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds. An intramolecular N-H⋯O interaction also occurs.

The structure of the title hydrated mol-ecular salt, C14H23N2O4 (+)·C2H3O2 (-)·H2O, was determined as part of a wider study on the use of the mol-ecule as a polydentate ligand in the synthesis of Mn(III) clusters with magnetic properties. The cation features intra-molecular O-H⋯N and N-H⋯O hydrogen-bond inter-actions. The crystal structure features a range of inter-molecular hydrogen-bonding in...

متن کاملAntioxidant Activity of 3-[N-(Acylhydrazono)ethyl]-4-hydroxy-coumarins.
A series of 3-acylhydrazono-4-hydroxycoumarins were synthesized via condensation of 3-acetyl-4-hydroxycoumarin with appropriate hydrazides. The structures of the newly-synthesized compounds were characterized by spectral and elememental analysis or HRMS measurements. Their antioxidant properties were evaluated by using scavenging effects on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical as well a...
