title: 2-[3,5-Bis-(4-fluoro-phen-yl)-4,5-dihydro-1H-pyrazol-1-yl]-4,6-bis(4-fluoro-phenyl)pyrimidine.
abstract: In the title compound, C(31)H(20)F(4)N(4), the pyrazole ring adopts an envelope conformation and forms a dihedral angle of 9.91 (6)° with the adjacent pyrimidine ring. The pyrimidine ring forms dihedral angles of 9.23 (6) and 2.16 (5)° with its adjacent fluoro-substituted benzene rings, whereas these angles are 88.22 (6) and 9.66 (6)° for the pyrazole ring and its adjacent benzene rings. In the crystal, mol-ecules are linked by C-H⋯F hydrogen bonds into ribbons along [01-1]. The crystal packing is further stabilized by C-H⋯π and by π-π inter-actions, with centroid-centroid distances of 3.7428 (7) and 3.7630 (6) Å.
