3,6-Di-4-pyridyl-1,4-dihydro-1,2,4,5-tetra-zine.

The mol-ecule of the title compound, C(12)H(10)N(6), which is V-shaped due to the boat conformation of the dihydro-tetra-zine ring, has crystallographic C(2) symmetry. The dihedral angle between the planes of the two pyridine rings is 31.57†(3)°. Mol-ecules are linked by weak N-H⋯N and C-H⋯N hydrogen bonds, forming a two-dimensional polymeric structure.
