4,6-Dimethyl­pyrimidin-2-amine

The asymmetric unit of the title compound, C₆H₉N₃, contains three crystallographically independent mol­ecules of similar geometry. All of the mol­ecules are almost planar, with r.m.s. deviations of 0.003, 0.016 and 0.005 Å. In the crystal, the mol­ecules are linked by N—H...N hydrogen bonds into zigzag ribbons parallel to the c axis, generating rings of R₂²(8) graph-set motif.
