title: 6-Fluoro-1,3,4-triphenyl-1H-pyrazolo[3,4-b]quinoline benzene hemisolvate.
abstract: In the title compound, C(28)H(18)FN(3)·0.5C(6)H(6), the 1H-pyrazolo[3,4-b]quinoline core is almost planar (r.m.s = 0.0371 Å, maximum deviation = 0.0571 Å) and aromatic. The solvent benzene mol-ecules are located around inversion centres. In the crystal, mol-ecules related by centres of symmetry form dimers, with distances of 3.932 (3) Å between best planes through the fused core due to π⋯π stacking. The phenyl substituents at positions 1, 3 and 4, are twisted away from the core, making dihedral angles of 29.66 (7), 44.59 (7) and 67.94 (6)°, respectively.
