Abstract: 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-H...N and O-H...O hydrogen bonds. The crystal packing is further stabilized by C-H...[pi] interactions involving a methylene group of the pyran ring and the C-attached benzene ring on the pyrazole ring.
