Abstract
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].Entities:

| Experimental. The crystal was placed in the cold stream of an Oxford Cyrosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K. |
| Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
