N-(5-Amino-2-methyl-phen-yl)-4-(3-pyri-dyl)-pyrimidin-2-amine
Abstract:
The title compound, C(16)H(15)N(5), crystallizes with two independent mol-ecules (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 mol-ecule A, and 6.8 (1) and 11.6 (9)° in mol-ecule B. The crystal packing is influenced by the collective action of weak inter-molecular N-H⋯N hydrogen bonds, a π-π stacking inter-action between neighbouring pyridyl rings of mol-ecule A [centroid-centroid distance = 3.8395 (10) Å] and C-H⋯π inter-actions.
