title: (3aR,6aR)-1-Phenyl-5-[(R)-1-phenyl-ethyl]-3-[4-(trifluoro-meth-yl)phen-yl]-1,6a-dihydro-pyrrolo[3,4-c]pyrazole-4,6(3aH,5H)-dione.
abstract: In the title mol-ecule, C(26)H(20)F(3)N(3)O(2), the two central five-membered rings form a dihedral angle of 62.94 (8)°. The absolute configuration was determined by analysis of Bijvoet pairs based on resonant scattering of light atoms, yielding a Hooft parameter y = -0.05 (11). Notable intra- and inter-molecular contacts include C-H⋯O and C-H⋯π(arene) hydrogen bonds.
