Equimolar quantities of 4-chloroaniline and 3,4-dimethoxybenzaldehyde were refluxed in methanol for 30 min. The solution was kept at room temperature which afforded orange light yellow prisms of (I) after 48 h.
The H-atoms were positioned geometrically (C–H = 0.93–0.96 Å) and refined as riding with Uiso(H) = xUeq(C), where x = 1.5 for methyl and x = 1.2 for other H-atoms.
The crystal structures of (II) i.e, 4-chloro-N-(3,4,5-trimethoxybenzylidene)aniline (Dehno Khalaji et al., 2009) and (III) i.e, 4-[(4-chlorophenyl)iminomethyl]-2-methoxyphenol (Shang & Tan, 2007) have been published which are related to the title compound (I, Fig. 1)
The title compound consists of two molecules in the crystallographic π···π interactions (Table 1).
which differ from each other geometrically. In one molecule, the 4-chloroanilinic group A (C1—C6/N1/CL1) and group B (C7—C13/O1/O2) of 3,4-dimethoxyphenyl are planar with r.m.s. deviation of 0.0081 and 0.0146 Å, respectively. The dihedral angle between A/B is 45.54 (4)°. The C-atoms C14 and C15 of 3,4-dimethoxyphenyl are at a distance of -0.0058 (35) and 0.1132 (34) Å, respectively from the parent group B. In the second molecule, the 4-chloroanilinic group C (C16—C21/N2/CL2) and group D (C22—C28/O3/O4) of 3,4-dimethoxyphenyl are planar with r.m.s. deviation of 0.0094 and 0.0063 Å, respectively. The dihedral angle between C/D is 19.68 (7)°. The C-atoms C29 and C30 of 3,4-dimethoxyphenyl are at a distance of -0.2256 (33) and -0.2205 (31) Å, respectively from the parent group D. This shows that both molecules differ at large from each other. The molecules are stabilized through C—H···O type of H-bonding andFor related structures, see: Dehno Khalaji et al. (2009); Shang & Tan (2007).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
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 crystal structures of (II) i.e, 4-chloro-N-(3,4,5-trimethoxybenzylidene)aniline (Dehno Khalaji et al., 2009) and (III) i.e, 4-[(4-chlorophenyl)iminomethyl]-2-methoxyphenol (Shang & Tan, 2007) have been published which are related to the title compound (I, Fig. 1)
The title compound consists of two molecules in the crystallographic asymmetric unit which differ from each other geometrically. In one molecule, the 4-chloroanilinic group A (C1—C6/N1/CL1) and group B (C7—C13/O1/O2) of 3,4-dimethoxyphenyl are planar with r.m.s. deviation of 0.0081 and 0.0146 Å, respectively. The dihedral angle between A/B is 45.54 (4)°. The C-atoms C14 and C15 of 3,4-dimethoxyphenyl are at a distance of -0.0058 (35) and 0.1132 (34) Å, respectively from the parent group B. In the second molecule, the 4-chloroanilinic group C (C16—C21/N2/CL2) and group D (C22—C28/O3/O4) of 3,4-dimethoxyphenyl are planar with r.m.s. deviation of 0.0094 and 0.0063 Å, respectively. The dihedral angle between C/D is 19.68 (7)°. The C-atoms C29 and C30 of 3,4-dimethoxyphenyl are at a distance of -0.2256 (33) and -0.2205 (31) Å, respectively from the parent group D. This shows that both molecules differ at large from each other. The molecules are stabilized through C—H···O type of H-bonding and π···π interactions (Table 1).
