To a solution of sodium cyanide (2 g) in water (18 ml) was added 4-formylbenzonitrile (2.62 g). The mixture was stirred for 15 min at room temperature, then a saturated sodium hydrosulfite solution (15 ml) was added dropwise. The resulting mixture was stirred at 293K until a yellow solid was obtained. The solid was filtered and recrystallized from a mixture of methanol (18 ml) and DMF (6 ml), to give crystals of the title compound suitable for X-ray
on slow evaporation of the solvents.All hydrogen atoms were placed at calculated positions and refined using the riding model approximation, with C—H = 0.93-0.97 Å and with Uiso(H) = 1.2 Ueq(C).

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. |

Benzonitriles and their derivatives are important starting materials in the synthesis of some heterocyclic molecules (Radl et al., 2000; Arıcı et al., 2004). As part of our ongoing study on benzonitrile derivatives (Zhao, 2008), the crystal structure of one such derivatives is reported here.
The molecular structure of the title compound (Fig. 1) shows normal bond lengths and angles. The C≡N triple bond and C=O double bond lengths are 1.142 (2) and and 1.193 (2) Å, respectively. The benzene ring are oriented nearly perpendicular to each other, the dihedral angle they form being 84.99 (7)°. In the crystal structure, centrosymmetrically-related molecules are linked into dimeric units by intermolecular C—H···N hydrogen bonds (Table 1) forming ten-membered rings of graph-set R22(10) (Berstein et al., 1995). These dimers are further connected by intermolecular C—H···O hydrogen interactions to form chains running parallel to the b axis.
