N-(5-Amino-2-methylphenyl)-4-(3-pyridyl)pyrimidin-2-amine
Abstract
The title compound, C16H15N5, crystallizes with two independent molecules (A and B) in the asymmetric unit. The dihedral angles of the pyrimidine ring with the benzene and pyridyl rings are 22.3 (1) and 53.2 (9)°, respectively, in molecule A, and 6.8 (1) and 11.6 (9)° in molecule B. The crystal packing is influenced by the collective action of weak intermolecular N—H...N hydrogen bonds, a π–π stacking interaction between neighbouring pyridyl rings of molecule A [centroid–centroid distance = 3.8395 (10) Å] and C—H...π interactions.
