N-(3-Methylphenyl)pyrimidin-2-amine
Two independent molecules comprise the asymmetric unit in the title compound, C(11)H(11)N(3). These differ in terms of the relative orientations of the aromatic rings: the first is somewhat twisted, while the second is approximately planar [dihedral angles between the pyrimidine and phenyl rings =...

Sumario: | Two independent molecules comprise the asymmetric unit in the title compound, C(11)H(11)N(3). These differ in terms of the relative orientations of the aromatic rings: the first is somewhat twisted, while the second is approximately planar [dihedral angles between the pyrimidine and phenyl rings = 39.00 (8) and 4.59 (11)°]. The molecules also form distinct patterns in their hydrogen bonding. The first independent molecule forms centrosymmetric dimers featuring an eight-membered {HNCN}(2) synthon. The second independent molecule forms an N—H⋯N hydrogen bond with the other pyrimidine N atom of the first molecule. Thereby, tetrameric aggregates are formed. These associate via C—H⋯N and C—H⋯π interactions, consolidating the crystal packing. |
