In the crystal structure of the title mol-ecule, C(13)H(14)N(4), the two pyridyl rings are not coplanar but twisted about the C-N bond with an inter-planar angle of 71.1 (1)°. In the crystal, the mol-ecules form dimers, situated on crystallographic centres of inversion, which are connected via a pair of N-H⋯N hydrogen bonds. C-H⋯π-electron ring(More)

In the crystal structure of the title compound, C(11)H(10)N(4), the dihedral angle between the two pyridyl rings is 36.1 (1)°. The mol-ecules are connected via two strong N-H⋯N and two weak C-H⋯N hydrogen bonds into dimers, which are located on centers of inversion. This compound adopts the s-trans-anti-s-cis conformation in the solid state.
