Abstract | |||||||||
| In the title compound, C19H16ClN5O2, the triazolopyrimidine ring system is essentially planar, with a maximum displacement of 0.021 (4) Å, and forms dihedral angles of 1.09 (9) and 87.74 (9)° with the phenyl and benzene rings, respectively. Short intramolecular C—H...O and C—H...N hydrogen-bonding interactions occur within the molecule. In the crystal structure, molecules are linked by intermolecular C—H...O hydrogen bonds into chains parallel to the b axis. In addition, π–π stacking interactions involving the triazole and pyrimidine rings of adjacent molecules are observed, with centroid–centroid distances of 3.600 (3) Å. | |||||||||
