In the title compound, C23H18N2O2·H2O, all bond lengths and angles are within normal ranges. The dihedral angles formed by the two phen­yl rings with the quinoline moiety are 61.40 (9) and 85.66 (8)°. The crystal packing is stabilized by inter­molecular C—H⋯O and O—H⋯O hydrogen bonds involving the solvent water mol­ecule.

In the title compound, C18H14FN3O2·CH4O, all bond lengths and angles are within normal ranges. The C18H14FN3O2 mol­ecule is essentially planar, with a dihedral angle of 7.83 (7)° between the planes of the benzene ring and the quinoline group. Each methanol mol­ecule is linked to one C18H14FN3O2 mol­ecule via inter­molecular N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds.

In the title compound, C17H14N2O2·0.5H2O, all bond lengths and angles are within normal ranges. The dihedral angle formed by the phen­yl ring with the quinoline moiety is 27.30 (9)°. The crystal packing is stabilized by inter­molecular N—H⋯O, C—H⋯O and O—H⋯N hydrogen bonds involv­ing the solvent water mol­ecule.
