3,6-Bis(4-chloro-phen-yl)-N,N-bis-(1-phenyl-eth-yl)-1,2,4,5-tetra-zine-1,4-di-carboxamide.

In the title mol-ecule, C(32)H(28)Cl(2)N(6)O(2), the amide-substituted N atoms of the tetra-zine ring deviate from the approximate plane of the four other atoms in the ring by 0.468†(3) and 0.484†(3)†à , forming a boat conformation. The dihedral angle between the two phenyl rings is 67.0†(1)° and that between the two chloro-substituted benzene rings is 73.8†(1)°. Two intra-molecular N-H⋯N hydrogen bonds are observed.
