title: 3-(4-Methyl-phen-yl)-4-[(thio-semi-carba-zono)meth-yl]-1,2,3-oxa-diazol-3-ium-5-olate 1,4-dioxane hemisolvate.
abstract: The asymmetric unit of the title compound, C11H11N5O2S·0.5C4H8O2, contains one 3-(p-tol-yl)sydnone 4-thio-semi-carba-zone mol-ecule and a half mol-ecule of 1,4-dioxane, which lies abount an inversion centre. The sydnone ring is almost planar, with a maximum deviation of 0.002 (1) Å, and forms a dihedral angle of 46.31 (5)° with the benzene ring. In the crystal, the two components are linked into a tape along [01-1] by N-H⋯O and N-H⋯S hydrogen bonds. The crystal structure is further stabilized by C-H⋯O and C-H⋯π inter-actions, forming a three-dimensional network.
