In the title compound, C19H18N2O3, the pyrazoline ring is close to being planar (r.m.s. deviation = 0.035 Å) and subtends dihedral angles of 2.11 (8) and 82.63 (8)° with the p-tolyl and benzene rings, respectively. In the crystal, C—HO and C—HN hydrogen bonds link the molecules, forming a three-dimensional network. A weak C—Hπ interaction involving the benzene ring is also observed.

The asymmetric unit of the title compound, C11H11N5O2S·0.5C4H8O2, contains one 3-(p-tolyl)sydnone 4-thiosemicarbazone molecule and a half molecule 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—HO and N—HS hydrogen bonds. The crystal structure is further stabilized by C—HO and C—Hπ interactions, forming a three-dimensional network.
