In the molecule of the title compound, C23H17N3O2, the methoxyphenyl ring is oriented at dihedral angles of 13.34 (12) and 88.83 (12)° with respect to the methylphenyl and phthalonitrile rings, respectively; the dihedral angle between methylphenyl and phthalonitrile rings is 89.67 (10)°. In the weak intermolecular C—H⋯N interactions link molecules into chains. A weak C—H⋯π interaction is also found..

For the preparation of the title compound, potasium carbonato (0.9 g, 6.58 mmol) was added to a solution of solid o-vaniline (0.5 g, 3.29 mmol) in DMF. The mixture was stirred for 30 min under nitrogen atmosphere. 4-Nitrophtalonitrile solution in DMF was added. The mixture was stirred for 48 h at 323 K under nitrogen atmosphere and poured into ice-water (150 g). The product 2-(3,4-dicyanophenoxy)-3-methoxybenzaldehyde was filtered off and washed with water. The title compound was prepared by refluxing a mixture of a solution containing 2-(3,4-Dicyanophenoxy)-3-methoxybenzaldehyde (0.5 g, 1.799 mmol) in ethanol (20 ml) and a solution containing 4-methylaniline (0.218 g 1.799 mmol) in ethanol (20 ml). The reaction mixture was stirred for 1 h under reflux. Crystals suitable for X-ray analysis were obtained from ethylalcohol by slow evaporation (yield; 55%, m.p. 427-429 K).
H atoms were positioned geometrically, with C-H = 0.93 and 0.96 Å for aromatic and methyl H, respectively, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C), where x = 1.5 for methyl H and x = 1.2 for aromatic H 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. |

Substituted phthalonitriles are generally used for preparing symmetrically and unsymmetrically peripherally and non-peripherally substituted phthalocyanines and subphthalocyanines (McKeown, 1998; Leznoff & Lever, 1989-1996). In addition to their extensive use as dyes and pigments, phthalocyanines have found widespread applications in catalysis, in optical recording, as photoconductive materials, in photo-dynamic therapy and as chemical sensors (Leznoff & Lever, 1989-1996). We report herein the crystal structure of the title compound.
In the molecule of the title compound (Fig. 1), the bond lengths (Allen et al., 1987) and angles are within normal ranges. The N2≡C22 [1.133 (3) Å] and N3≡C23 [1.145 (3) Å] bonds show N≡C triple bond character and are in good agreement with the literature values (Ocak İskeleli et al., 2005). Rings A (C1-C6), B (C9-C14) and C (C16-C21) are, of course, planar, and they are oriented at dihedral angles of A/B = 13.34 (12), A/C = 88.83 (12) and B/C = 89.67 (10) °.
In the crystal structure, weak intermolecular C-H···N interactions (Table 1) link the molecules into chains (Fig. 2), in which they may be effective in the stabilization of the structure. There also exists a weak C-H···π interaction (Table 1).
