Mol-ecules of the title compound, C(13)H(13)N(3), are essentially planar (r.m.s. deviation for all non-H atoms = 0.054 Å). The dihedral angle between the two aromatic rings is 6.33 (5)°. In the crystal, pairs of centrosymmetrically related mol-ecules are linked through N-H⋯N hydrogen bonds, forming N-H⋯N dimers with graph-set motif R(2) (2)(8).

Nicotine-based ionic liquid has been used as a green catalyst for pyridine-catalyzed Huisgen reaction. It promoted addition of dimethylacetylenedicarboxylate to aldehydes or N-tosyl imines leading to efficient synthesis of 2-benzoylfumarates and 1-azadienes respectively under pyridine free odorless ionic liquid conditions. The improved results were obtained in terms of enhanced yields, with min...

In the title mol-ecule, C(12)H(12)N(6), the dihedral angles between the pyridine rings and the central dimethan-imine-hydrazine group are 0.30 (3) and 13.94 (3)°. Two intra-molecular N-H⋯N hydrogen bonds stabilize the planar conformation of one pyridine ring with respect to its hydrazine-residue neighbour, whereas the other pyridine ring and an N-bonded H atom are rotated out of the plane and l...
