In the title compound, C27H19N3O, the dihedral angles between the plane of the pyridine ring and those of the indole (r.m.s. deviation = 0.018 Å), phenyl and methoxybenzene substituents are 33.60 (6), 25.28 (7) and 49.31 (7)°, respectively. The N atom of the carbonitrile group is significantly displaced [0.288 (2) Å] from the plane of the pyridine ring, perhaps due to steric crowding. In the crystal, inversion dimers linked by pairs of N—H⋯Nn (n = nitrile) hydrogen bonds generate R22(16) loops. Aromatic π–π stacking [centroid–centroid separation = 3.6906 (7) Å] and very weak C—H⋯π interactions are also observed".

A mixture of 3-(1H-indol-3-yl)-3-oxopropanenitrile 1 (1 mmol), 4,4,4-trifluoro-1- phenylbutane-1,3-dione 2 (1 mmol) and 4-methoxy benzaldehyde 3 (1 mmol) in the presence of ammonium acetate (400 mmol) under solvent-free condition was heated at 110°C for 7 h. After completion of the reaction (TLC), the reaction mixture was poured into water and extracted with dichloromethane. After removal of the solvent, the residue was chromatographed over σilica gel (230–400 mesh) using petroleum ether-ethyl acetate mixture (7:3 v/v), which afforded the pure compound.
Melting point:265 °C, Yield: 72%.
H atoms were placed at calculated positions and allowed to ride on their carrier atoms with C—H = 0.93–0.98 Å and with Uiso = 1.2Ueq(C, N) for N, CH2 and CH atoms and Uiso = 1.5Ueq(C) for CH3 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. |

Derivatives of 3-cyanopyridine are important and useful intermediates in preparing a varity of heterocyclic compounds (Shishoo et al., 1983). Therefore, the synthesis of 3-cyanopyridine derivatives attracts much interest in organic chemistry. It was in this context that the title compound, was investigated.
The deviation of the nitrile atoms (C41,N2) from the mean plane of the pyridine ring system is -0.1497 (1) Å and -0.2886 (5) Å. The shortening of the C—N distances [1.337 (3) and 1.341 Å] and the opening of the N1–C11–C10 angle [121.15 (2)°] may be attributed to the size of the substituent at C1, correlating well with the values observed in the ortho-substituted derivative. The dihedral angle between the pseudo-axial phenyl substituent and the plane of the pyridine ring is 69.13 (8)°.
The crystal structure features an N—H···N interaction between inverse related molecules generating a graph set ring motif R22 (16) which are linked into chains through C—H···Cg1 interation (Cg1 is the centroid of the pyrrole ring of the indole moiety) and by π···π stacking interaction involving adjacent pyridine rings of the symmetry related molecule at (1-X,1-Y,-Z), with a centroid-to-centroid distance of 3.6906 (7) Å·(Fig 2).
