Abstract:
In the title mol-ecule, C14H10N6O, the planes of the methyl-furazan fragment and the phenyl ring attached to the triazolo-pyrimidine bicycle are twisted from the mean plane of the bicycle at angles of 45.92 (5) and 5.45 (4)°, respectively. In the crystal, π-π inter-actions, indicated by short distances [in the range 3.456 (3)-3.591 (3) Å] between the centroids of the five- and six-membered rings of neighbouring mol-ecules, link the mol-ecules into stacks propagating along the c-axis direction.
