In the title compound, C26H16ClN3, the dihedral angles between the central pyridine ring and the pendant phenyl, chlorobenzene and indole rings are 18.52 (12), 48.97 (11) and 21.20 (10)°, respectively. An intramolecular C—H⋯Nc (c = cyanide) hydrogen bond occurs. In the crystal, inversion dimers linked by pairs of N—H⋯Nc hydrogen bonds generate R22(16) loops.
Keywords: crystal structure; pyridine-3-carbonitrile; hydrogen bonding.

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-chloro benzaldehyde 3 (1 mmol) in the presence of ammonium acetate (400 mmol) under solvent-free condition was heated at 110 °C for 6 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 silica gel (230–400 mesh) using petroleum ether-ethyl acetate mixture (7:3 v/v), which afforded the pure compound. Melting point:273 °C, Yield: 70%.
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. |

Thienopyridines have been used as antithrombotic agents (Yao et al., 1994) against platelet aggregation. As part of our ongoing studies in this area (Vishnupriya et al., 2014) the title compound was investigated.
The deviation of the nitrile atoms (C41,N2) from the mean plane of the pyridine ring system is 0.0579 (5) and 0.0826 (2) Å. The shortening of the C—N distances [1.340 (3) and 1.348 (3) Å] and the opening of the N1–C4–C5 angle [120.83 (2)°] may be attributed to the size of the substituent at C1, correlating well with the values observed in the ortho-substituted derivative. The carbonitrile group lies almost in the plane of the attached planar pyridine ring system.
The crystal structure features a N3—H3···N2(i) [symmetry code: (i) 2 - x, 2 - y, -z] hydrogen bonded R22 (16) motif (Fig. 2). No significant π—π stacking interaction between neighboring aromatic rings or C—H···π interaction towards them are observed.
