In the title compound, C(25)H(26)N(2)O(3), the double bond connecting the aza-bicyclic and indole units has Z geometry. The compound was obtained as a racemate, and since the crystal is centrosymmetric it contains equal amounts of the S and R enanti-omers. However, the structure is disordered such that the asymmetric unit contains both enanti-omers in unequal amounts [refined occupancies 0.904 (2) and 0.096 (2)]. The dihedral angle between the benzene ring of the benzyl group and the mean plane of the indole ring is 76.07 (3) °. In the crystal, mol-ecules are linked by O-H⋯O(carbon-yl) hydrogen bonds into chains propagating in [110].

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)°.

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.
