In the title compound, C(12)H(13)ClN(4)O(2), the triazole ring carries methyl and ethoxy-carbonyl groups, and is bound via a methyl-ene bridge to a chloro-pyridine unit. There is evidence for significant electron delocalization in the triazolyl system. Intra-molecular C-H⋯O and inter-molecular C-H⋯N hydrogen bonds stabilize the structure.
