N(1),N(4),3,6-Tetra-methyl-1,2,4,5-tetra-zine-1,4-dicarboxamide.

ABSTRACT: The asymmetric unit of the title compound, C(8)H(14)N(6)O(2), contains two independent mol-ecules. In one mol-ecule, the amide-substituted N atoms of the tetra-zine ring deviate from the plane [maximum deviation = 0.028?(1)?Å] through the four other atoms in the ring by 0.350?(2) and 0.344?(2)?Å, forming a boat conformation, and the mean planes of the two carboxamide groups form dihedral angles of 10.46?(13) and 20.41?(12)° with the four approximtely planar atoms in the tetra-zine ring. In the other mol-ecule, the amide-substituted N atoms of the tetra-zine ring deviate from the plane [maximum deviation = 0.033?(1)?Å] through the four other atoms in the ring by 0.324?(2) and 0.307?(2)?Å, forming a boat conformation, and the mean planes of the two carboxamide groups form dihedral angles of 14.66?(11) and 17.08?(10)° with the four approximately planar atoms of the tetra-zine ring. In the crystal, N-H?O hydrogen bonds connect mol-ecules to form a two-dimensional network parallel to (1-1-1). Intra-molecular N-H?N hydrogen bonds are observed.
