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.

The asymmetric unit of the title compound, C29H24FNO5·0.5CH3OH, contains two independent molecules and a one methanol solvent molecule. The methanol molecule is O—HO hydrogen bonded to one of the independent molecules. The pyrrolidine rings in both molecules adopt half-chair conformations, while the cyclopentane rings within the indane groups are in flattened envelope conformations, with the spiro C atoms forming the flaps. The benzene rings of the indane ring systems form a dihedral angle of 35.06 (7)° in one independent molecule and 31.16 (8)° in the other. The fluoro-substituted benzene ring forms dihedral angles of 65.35 (6) and 85.87 (7)° with the indane group benzene rings in one molecule, and 72.78 (8) and 77.27 (8)° in the other. In each molecule, a weak intramolecular C—HO hydrogen bond forms an S(6) ring motif. In the crystal, weak C—HO, C—HN and C—HF hydrogen bonds link the molecules into a three-dimensional network.
