Charge-assisted N-H•••I and C-H•••I hydrogen bonding in (1R,2S)-1-(ferrocenylmethyl)-2-(methoxymethyl)pyrrolidinium iodide

In the title compound, [Fe(C5H5)(C12H19NO)] I, the ferrocene moiety has an eclipsed conformation, with mean Fe - C bond lengths of 2.031 ( 4) and 2.020 ( 6) Angstrom for the substituted and unsubstituted cyclopentadienyl rings. The pyrrolidinium heterocycle adopts an envelope conformation and has its 1- and 2-substituents in a relative trans disposition. Strong (+/-)-charge- assisted N - H ... I and C - H ... I hydrogen bonds are present. The crystal structure is also stabilized by weak C H ... O interactions.
