4-(4-Bromo-phen-yl)-6-(4-chloro-phen-yl)-pyrimidin-2-ylamine

The title compound, C(16)H(11)BrClN(3), contains pairs of mol-ecules lying about inversion centers linked by amino-pyrimidine N-H⋯N hydrogen bonds. The eight-membered rings thus formed are represented by the R(2) (2)(8) motif in graph-set notation. The second H atom of the amine group shows a rather weak inter-action with two Br atoms, resulting in bifurcated N-H⋯(Br,Br) hydrogen bonds. The dihedral angles between the mean planes of the benzene rings and the mean plane of the heterocyclic ring are 8.98 (15) and 35.58 (10)°. The Br and Cl atoms show substitutional disorder, with site-occupancy factors of 0.599 (2) and 0.401 (2), respectively.
