摘要

The title compound, C13H12ClN5, was synthesized by the cyclization of 1-(4,6-di­methyl­pyrimidin-2-yl)-4-phenyl­thio­semicarbazide in the presence of Ni(NO3)2. The mol­ecular structure of the compound is essentially planar. In the crystal, mol­ecules form dimers via pairs of N—H⋯N hydrogen bonds between the H atom of the exocyclic amino group and the N atom at the 4-position of the triazole ring. The resulting dimers are packed into layers which are connected by π-stacking inter­actions between the aromatic systems of the pyrimidine and benzene nuclei, and between the triazole cores.
