The title compound (I) was synthesized according to the procedure of Andersen et al. (1988). Colorless single crystals (m.p. 403–404 K) were obtained by slow evaporation of a solution in absolute alcohol.
C-bound H atoms were positioned geometrically and refined in the riding-model approximation, with d(C—H) = 0.93 Å, Uiso=1.2Ueq (C) for aromatic, 0.96 Å, Uiso = 1.5Ueq (C) for CH3 atoms and 0.97 Å, Uiso = 1.2Ueq (C) for CH2 atoms.

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. |

Aromatic amines are widely employed for organic synthesis, especially as dye intermediates. One method for preparing aromatic amines is reduction of the corresponding aromatic nitro compound (Lauwiner et al., 1998). In our recent work, the title compound (I), Fig. 1, was reduced to the corresponding aromatic amine for potential use as an intermediate in the synthesis of Acid Blue 264 dye according to Yang et al. (2004).
In (I), all bonds lengths and angles are normal (Allen et al., 1987). The dihedral angle between the two aryl rings is 63.30 (8) Å. The distances of S1—C1 and S1—N1 are 1.762 (3) and 1.637 (2) Å respectively. The neighboring molecules are linked together by weak C—H···O hydrogen bonds, Table 1.
