Comment top

In order to further explore the biological significance of hydrazides, we have prepared the title compound (I). It was found to be active against DPPH radical scavenging activity and inactive against all fungal strains (Maqsood et al. 2006). The crystal structures of trimethoxybenzohydrazide (Saeed et al. 2008, Zareef et al. 2006) and para hydroxybenzohydrazide (Jamal et al. 2009) analogues of (I) have already been reported.

The molecular structure of (I) is composed of a hydrazide moiety attached to the phenyl ring (Fig. 1). The phenyl ring is almost planar with a maximum deviation of 0.009 (1) Å from the least-squares plane. The bond lengths and angles all are in normal range as in other structurally related compounds (Saeed et al. 2008; Zareef et al., 2006). In the crystal, the molecules are linked to form three-dimensional molecular network via O1—H1A···O2, N1—H1B···O1, O2—H2A···N2, N2—H2B···O3, N2—H2C···O4 and O3—H3A···O4 intermolecular hydrogen bonds (Tab. 1 & Fig. 2).

Experimental top

To a solution of methyl-3,4,5-trihydroxybenzoate (3.68 g, 20 mmol) in 75 ml ethanol, hydrazine hydrate (5.0 ml, 100 mmol) was added. The mixture was refluxed for 5 h and a solid was obtained upon removal of the solvent by rotary evaporation. The resulting solid was washed with hexane to afford 3,4,5-trihydroxybenzohydrazide (yield 87%) (Maqsood et al., 2006). Colourless blocks of (I) were grown from a solution of methanol by slow evaporation at room temperature.

Refinement top

The H atoms on the N atoms (N–H= 0.92 (2)–0.86 (19) Å) O atoms (O–H= 0.91 (3)–0.85 (19) Å) and Carbon (C–H= 0.961 (18)–0.955 (17) Å) atoms were located in difference Fourier maps and refined isotropically.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
