To a solution of 4-formylbenzonitrile (6.55 g, 0.05 mol) in methanol (40 ml) was added phenylhydrazine (5.40 g, 0.05 mol) with stirring at room temperature. After 20 minutes, a mass of yellow precipitate appeared and was filtered. The crude product was recrystallized by slowly evaporating an ethanol solution to yield pale yellow block-like crystals, suitable for X-ray analysis.
Positional parameters of all the H atoms were calculated geometrically and were allowed to ride on the C atoms to which they are bonded, with d(C—H) = 0.93 and d(N—H) = 0.90 Å and Uiso(H) = 1.2Ueq(C or N). In the absence of significant anomalous scattering effects, Friedel pairs were merged.

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. |

Nitrile compounds are the precursor of tetrazole derivatives (Dunica, et al., 1991; Wittenberger, et al., 1993), which we have focused on for the design of noncentrosymmetric bulk materials (Xiong, et al.(2002)). We report here the crystal structure of the title compound, 4-(phenyl-hydrazonomethyl)benzonitrile, (I), Fig. 1.
In I, the C=N double bond (1.359 (4) Å) is in the range 1.34–1.38 Å found in other similar hydrazone complexes with a trans configuration (Szczesna & Urbanczyk-Lipkowska (2002); Drew, et al.(1984). The torsion angles of C9 - N2 - N1 - C1 is -178.7 (3)°. Dihedral angle between the two benzene rings is 13.56 (0.15) °. In the crystal structure molecules related by translation along b axis are connected by N2—H2B···N3 hydrogen bonds resulting in the formation of one dimensional chains along the b axis.
