4-methoxybenzohydrazide (0.01 mol,1.66 g) was dissolved in anhydrous ethanol (50 ml), and (3,5-dichloro-2-hydroxyphenyl)(phenyl)methanone (0.01 mol, 2.67 g) was added. The reaction mixture was refluxed for 6 h with stirring, then the resulting precipitate was collected by filtration, washed several times with ethanol and dried in vacuo (yield 78%). The compound (1.0 mmol,0.41 g) was dissolved in dimethylformamide (30 ml) and kept at room temperature for 20 d to obtain colourless single crystals suitable for X-ray diffraction.
All H atoms were positioned geometrically and treated as riding on their parent atoms,C—H(methyl) = 0.96 Å,C—H(aromatic) = 0.93 Å, O—H = 0.82 Å, and N—H =0.86 Å and with Uiso(H) =1.5U~eq~(C~methyl~,O) and 1.2Ueq(Caromatic,N).
The chemistry of aroylhydrazones continues to attract much attention due to their coordination ability to metal ions and their biological activity (Salem, 1998; Chang et al., 2007).As an extension of work on the structural characterization of aroylhydrazone derivatives,the title compound, (I),was synthesized and its
is reported here.The title molecule displays a
conformation with respect to the C7=N2 double bond (Fig. 1). The three benzene rings, C1–C6 (A), C9–C14 (B) and C16–C21 (C) make dihedral angles of 10.69 (15)(A/B) °, 79.64 (13) (B/C) °, 73.13 (12)(A/C) °. The is stabilized by intramolecular O—H···N hydrogen bond.(Table 1.) .For related compounds, see: Salem (1998); Chang & Ji (2007).

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. |

The chemistry of aroylhydrazones continues to attract much attention due to their coordination ability to metal ions and their biological activity (Salem, 1998; Chang et al., 2007).As an extension of work on the structural characterization of aroylhydrazone derivatives,the title compound, (I),was synthesized and its crystal structure is reported here.
The title molecule displays a trans conformation with respect to the C7=N2 double bond (Fig. 1). The three benzene rings, C1–C6 (A), C9–C14 (B) and C16–C21 (C) make dihedral angles of 10.69 (15)(A/B) °, 79.64 (13) (B/C) °, 73.13 (12)(A/C) °. The molecular conformation is stabilized by intramolecular O—H···N hydrogen bond.(Table 1.) .
