2-Amino-6-(piperidin-1-yl)-4-p-tolyl­pyridine-3,5-dicarbo­nitrile

In the title compound, C₁₉H₁₉N₅, the piperidine ring adopts a chair conformation. The pyridine ring is essentially planar, with a maximum deviation of 0.039 (2) Å for a C atom substituted with a carbonitrile group. The mean plane of the central pyridine ring makes the dihedral angles of 37.90 (14) and 56.10 (12)° with the piperidine and benzene rings, respectively. In the crystal, mol­ecules are linked via N—H...N and C—H...N hydrogen bonds, forming chains along [101], and enclosing R₂²(17) ring motifs. The chains are linked by further C—H...N hydrogen bonds, forming two-dimensional networks lying parallel to (10-1), and enclosing inversion dimers with R₂²(20) ring motifs.
