1'-(1,3-Diphenyl-1H-pyrazol-4-yl)-2',3',5',6',7',7a'-hexahydro-1'H-dispiro[acenaphthylene-1,3'-pyrrolizine-2',3''-chromane]-2,4''(1H)-dione

Abstract: In the title compound, C41H31N3O3, the pyrazole and pyrrolidine rings adopt twisted conformations. The mean plane of the pyrazole ring forms dihedral angles of 9.11 (12) and 39.65 (11)° with the phenyl rings. The O atoms deviate from the mean planes of the chromene and acenaphthylene ring systems by 0.194 (15) and 0.079 (15) Å, respectively. In the crystal, molecules are linked via pairs of C-H...O interactions,forming inversion dimers with an R22(12) ring motif.
