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(More)
In the title compound, C(13)H(13)N(3), the cyano groups at the 2- and 5-positions are eclipsed with each other. The phenyl ring is disordered over two sets of sites, with refined occupancies of 0.520 (5) and 0.480 (5). The angles between the mean plane of the pyrrolidine ring and the two cyano groups are 71.7 (9) and 75.0 (12)°.
