4,6-Dimeth-oxy-2-(methyl-sulfan-yl)pyrimidinium chloride

In the title compound, C(7)H(11)N(2)O(2)S(+)·Cl(-), the 4,6-dimeth-oxy-2-(methyl-sulfan-yl)pyrimidinium cation is essentially planar (r.m.s. deviation = 0.043 Å). In the crystal, the anions and cations are connected by inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds, forming a two-dimensional network parallel to (011). Adjacent networks are cross-linked via π-π inter-actions involving the pyrimidinium ring [centroid-centroid distance = 3.5501 (8) Å].
