The title compound, C(11)H(11)N(3), crystallizes with two mol-ecules (A and B) in the asymmetric unit. The geometries of both mol-ecules are very similar, with the exception of the torsion angles of the inter-ring chains; the values for C-N-C-C are 67.4 (5) and -69.3 (5)° for mol-ecules A and B, respectively. The dihedral angles between the pyridyl ring planes are 84.0 (2) and 83.2 (2)° for mol-ecules A and B, respectively. In the crystal, weak inter-molecular N-H⋯N hydrogen bonds and C-H⋯π inter-actions contribute to the stabilization of the packing.
