Abstract
The title compound, N-(4-chlorophenyl)-5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidin-2-amine, was synthesized by cyclization of 1-(4,6-dimethylpyrimidin-2-yl)-4-phenylthiosemicarbazide in the presence of Ni(NO3)2. In the crystal, molecules form inversion dimers via pairs of N—H⋯N hydrogen bonds, which are packed into layers by π-stacking interactions between the aromatic systems of neighbouring molecules.
