چکیده
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].

The base mol-ecule of the title co-crystal, C7H10N2O2S·C7H6O3, is essentially planar, with a maximum deviation of 0.0806 (14) Å for all non-H atoms. The acid mol-ecule is also nearly planar, with a dihedral angle of 8.12 (14)° between the benzene ring and the carb-oxy group. In the crystal, the acid mol-ecules form an inversion dimer through a pair of O-H⋯O hydrogen bonds with an R2(2)(8) ring ...

In the title mol-ecule, C(10)H(16)O(3)S(4), a short intra-molecular S⋯O(=C) distance [2.726 (2) Å] indicates the presence of a nonbonding attractive inter-action. In the crystal, mol-ecules are linked into centrosymmetric dimers via weak inter-molecular C-H⋯O and S⋯S [3.405 (3) Å] inter-actions. These dimers are linked by further weak C-H⋯O inter-actions into columns along the a axis.
