4-Hydroxy-N'-(4-methoxybenzylidene)benzohydrazide

D.-H. Shi

Abstract top

The title compound, C15H14N2O3, was synthesized by the reaction of 4-methoxybenzaldehyde with 4-hydroxybenzohydrazide in methanol. The molecule adopts an E configuration about the C=N bond. The two benzene rings make a dihedral angle of 46.6 (2)°. In the crystal structure, molecules are linked into a two-dimensional network parallel to (001) through O-H...O and N-H...O hydrogen bonds.

Comment top

Hydrazone compounds are a kind of important materials in biological and medicinal chemistry. They have been widely investigated for their antibacterial activities (Cukurovali et al., 2006). Recently, a number of hydrazone compounds have been prepared and structurally characterized (Abdul Alhadi et al., 2009; Mohd Lair et al., 2009; Cao & Lu, 2009; Qu & Cao, 2009). In this paper, the author reports the crystal structure of the title hydrazone compound.

The molecule of the title compound adopts an E configuration about the CN bond (Fig. 1). The two benzene rings make a dihedral angle of 46.56 (7)°. The C8/N1/N2/C9/O2 plane makes dihedral angles of 8.2 (1) and 54.5 (1)°, respectively, with the C1—C6 and C10—C15 benzene rings. All the bond lengths are normal (Allen et al., 1987).

In the crystal structure, molecules are linked through N—H···O and O—H···O hydrogen bonds (Table 1), forming a two-dimensional network parallel to the (001) [Fig. 2].

Experimental top

4-Methoxybenzaldehyde (13.6 mg, 0.1 mmol) and 4-hydroxybenzohydrazide (15.2 mg, 0.1 mmol) were mixed and refluxed in a methanol solution. After 30 min, the clear solution was evaporated to give colourless crystallites, which were recrystallized from methanol to form single crystals.

Refinement top

Atom H2A was located in a difference Fourier map and refined isotropically, with the N-H distance restrained to 0.90 (1) Å. Other H atoms were placed in calculated positions [O-H = 0.82 Å and C-H = 0.93–0.96 Å] and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(O and C7).

Special details top

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.
