Abstract

In the cation of the title solvated molecular salt, C12H 14- ClN4+·C14H 8F3O2S-·C2H 6OS systematic name of the cation: 2,4-diamino-5-(4-chlorophenyl)-6- ethylpyrimidin-1-ium, the dihedral angle between the planes of the pyrimidinium and 4-chlorophenyl rings is 77.2 (5)°. In the anion, the planes of the benzene rings are twisted with respect to each other by 71.5 (5)°. Disorder was modelled for the dimethyl sulfoxide solvent molecule over two set of sites in a 0.7487 (13): 0.2513 (13) ratio. In the crystal, the cations are linked by inversion-generated pairs of N-H�N hydrogen bonds, with an R 22(8) graph-set motif. The cation donates two N-H�O hydrogen bonds to the anion, also generating an R22(8) loop. These interactions, along with cation-solvent N-H�O hydrogen bonds, and cation-anion C-H�F, solvent-anion C-H�O and C-H�F interactions, result in a threedimensional network.
