title: 4-Amino-2,6-dimethoxypyrimidine: hydrogen-bonded sheets of R22(8) and R66(28) rings, reinforced by an aromatic pi-pi-stacking interaction.
abstract: Molecules of the title compound, C(6)H(9)N(3)O(2), are linked by an N-H.O hydrogen bond [H.O = 2.29 A, N.O = 3.169 (2) A and N-H.O = 173 degrees ] and an N-H.N hydrogen bond [H.N = 2.12 A, N.N = 2.999 (2) A and N-H.N = 175 degrees ] into sheets containing centrosymmetric R(2)(2)(8) and R(6)(6)(28) rings; the sheets are reinforced by a single aromatic pi-pi-stacking interaction.
