The title compound, C13H13ClN4O2, contains both a phenyl and a triazole ring, both of which are approximately coplanar with the entire molecule. The triazole ring has substituents at the 1-, 2- and 4-positions. Intramolecular C-H...O and C-H...N interactions, together with intermolecular C-H...O and C-H...pi interactions, help to stabilize the structure.
