The 6-amino- 1,3-dimethyluracil molecule [6-amino- 1,3-
dimethyl-2,4(1H,3H)-pyrimidinedione], C6H9N302 (I),
lies on a crystallographic mirror plane and participates
in an extensive two-dimensional hydrogen-bonding network
in the solid state. Each molecule is involved in N--
H...O=C hydrogen bonding involving the amino and
carbonyl gr. oups, with O...N separations of 2.894 (3) and
2.904 (3) A.
