(3,6-Dimethyl-1,2,4,5-tetra­zine-1,4-di­yl)bis­[(morpholin-4-yl)methanone]

In the title mol­ecule, C₁₄H₂₂N₆O₄, the amide-substituted N atoms of the tetra­zine ring deviate from the approximate plane of the four other atoms in the ring by 0.160 (2) and 0.243 (2) Å, forming a slight boat conformation. The morpholine rings are in chair conformations.

3,6-Dimethyl-N¹,N⁴-bis­(pyridin-2-yl)-1,2,4,5-tetra­zine-1,4-dicarboxamide

In the title mol­ecule, C₁₆H₁₆N₈O₂, four atoms of the tetra­zine ring are coplanar, with the largest deviation from the plane being 0.0236 (12) Å; the other two atoms of the tetra­zine ring deviate on the same side from this plane by 0.320 (4) and 0.335 (4) Å. Therefore, the central tetra­zine 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.
