2-(4-Hy­droxy­phen­yl)-4,6-dimethyl-2,3-di­hydro­pyrimidin-1-ium acetate

In the title compound, C12H15N2O+·C2H3O2−, the phen­oxy group is nearly perpendicular [80.73 (11)°] to the di­hydro­pyrimidinium ring. In the crystal, O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds form corrugated layers parallel to the ac plane.
