3,6-DimethyI-N-1, N-4-bis(pyridin-2-yI)-1,2,4,5-tetrazine- 1,4-dicarboxamide

In the title molecule, C 16H 16N 8O 2, four atoms of the tetra-zine ring are coplanar, with the largest deviation from the plane being 0.0236 (12) Å; the other two atoms of the tetra-zine ring deviate on the same side from this plane by 0.320 (4) and 0.335 (4) Å. Therefore, the central tetra-zine ring exhibits a boat conformation. The dihedral angles between the mean plane of the four coplanar atoms of the tetrazine ring and the two pyridine rings are 26.22 (10) and 6.97 (5)°. The two pyridine rings form a dihedral angle of 31.27 (8)°. In the molecule, there are a number of short C - H⋯O interactions. In the crystal, molecules are linked via a C - H⋯O interaction to form zigzag chains propagating along the [010] direction.
