7-Dimethyl-amino-2-phenyl-1,2,4-triazolo[1,5-a][1,3,5]triazin-5-amine methanol solvate

Abstract

7-Dimethyl-amino-2-phenyl-1,2,4-triazolo[1,5-a][1,3,5]triazin-5-amine crystallized with one mol-ecule of methanol to give the title compound, C 12H13N7·CH3OH. The triazolo[1,5-a][1,3,5]triazine heterocyclic core is essentially planar as are both amino groups that are involved in π-electron delocalization with the triazolo[1,5-a][1,3,5]triazine nucleus. The methyl groups of the dimethyl-amino fragment are involved in the formation of weak intra-molecular C - H...N hydrogen bonds with the N atoms of the heterocyclic system. The crystal packing is stabilized by inter-molecular N - H...N hydrogen bonds between the triazolo[1,5-a][1,3,5]triazine mol-ecules. The methanol solvent mol-ecule also participates in the formation of the crystal structure via inter-molecular O - H...N, N - H...O and weak C - H...O hydrogen bonds, linking the layers of triazolo[1,5-a][1,3,5]triazine mol-ecules.
