## Abstract The condensation of malonoaldehyde derivatives with either a 3‐amino‐[1,2,4]‐triazole or a 3,5‐diamino‐[1,2,4]‐triazole precursor was studied. In agreement with previous reports, two different bicycles, namely, bearing the regioisomeric [1,2,4]triazolo[1,5‐a]pyrimidine (**1**) or[1,2,4]

The cation of the title molecule, C~5~H~5~N~4~ ^+^·Cl^−^, is strictly planar; it occupies a special position on a mirror plane. The protonation of the heterocycle takes place, as expected, at an N atom of the imidazole ring. This H atom is hydrogen bonded to the chloride anion.
