In the central aza-bicyclooctane unit of the title compound, C40H34N4O3·0.75H2O, the peripheral pyrrolidine ring adopts an envelope conformation with the N atom deviating by 0.209 (2) Å, whereas the other pyrrolidine ring adopts a twisted conformation with the bridging N and C atoms deviating by −0.218 (2) and 0.236 (3) Å, respectively, from the rest of the ring. The pyrazole ring forms dihedral angles of 42.36 (7) and 24.07 (8)° with its C- and N-attached phenyl groups, respectively. The solvent water molecule has a partial occupancy of 0.75. In the crystal, the water molecules link the fused-ring molecules into chains along the b axis via O—HN and O—HO hydrogen bonds. The crystal packing is further stabilized by C—Hπ interactions involving a methylene group of the pyran ring and the C-attached benzene ring on the pyrazole ring.

In the title compound, C31H25N5O3·C2H6OS, the three indole/indoline units are all essentially planar with maximum deviations of 0.0172 (3), 0.053 (2) and 0.07 (2) Å. The pyrrolidine ring adopts an envelope conformation with the C atoms bearing the 1-ethyl-2-oxoindole substituent (in which the five-membered ring adopts a twisted conformation) as the flap. The dimethyl sulfoxide solvent molecule is disordered over two positions, with an occupancy factor ratio of 0.871 (4):0.129 (4). The solvent components are linked to the heterocyclic molecule via C—HO and C—HS hydrogen bonds. In the crystal, the solvent components are linked to the heterocyclic molecule via C—HO and C—HS interactions, forming R22(10) ring motifs. The molecules are further connected into a chain along the a-axis direction via N—HO hydrogen bonds.
