title: 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(12)H(13)N(7)·CH(3)OH. 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.
