In the title compound, C(22)H(28)F(2)NO(2) (+)·CHO(2) (-), there are three independent pyrrolidinium formate salt mol-ecules. In each cation, the central pyrrolidinium ring is not planar and the 2,5-disubstituted phenyl-ethyl groups are in equatorial positions. In the crystal, the ions are linked into a pair of chains parallel to the c axis by N-H⋯O hydrogen bonds between the NH group of the pyrrolidinium ring and the formate O atoms.
