In the title molecule, C15H15ClN2, the dihedral angle between the aromatic is 64.1 (2)°.
A mixture of 4-(dimethylamino)benzaldehyde (0.01 mol) and 2-chlorobenzenamine (0.01 mol) in ethanol (10 ml) was refluxed for 2 h. After cooling, filtration and drying, the title compound was obtained. 10 mg of (I) were dissolved in 15 ml of ethanol, and the solution was kept at room temperature for 5 d. Natural evaporation gave light yellow single crystals of the title compound, suitable for X-ray analysis.
H atoms were initially located from difference maps and then refined in a riding model with C—H = 0.93–0.96 Å and Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl 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. |

Schiff base compounds have been used as fine chemicals and medical substrates and they are important ligands in coordination chemistry due to their ease of preparation and their ability to be modified both electronically and sterically. In this paper, the structure of the title compound, (I), is reported. The molecular structure of (I) is illustrated in Fig. 1. The bond lengths and angles in the title molecule are similar to the related compound 4-chloro-N-[4-(dimethylamino)benzylidene]aniline (You et al., 2004). The 4-(Dimethylamino)benzylidene system is nearly planar to within 0.035 (3) A°. 2-Chlorobenzenamine system is nearly planar to within 0.060 (3) A°. The dihedral angle between these two systems is 67.0 (2) °.
