Abstract: The title compound, [Fe(C₅H₅)(C₂₁H₂₄NPS)]I·CHCl₃, is built up from a (ferrocenylmethyl)trimethylammonium cation, a iodine anion and a chloroform solvent molecule, all residing in general positions. The N atom of the ammonium group is displaced by 1.182 (2) Å from the plane of the substituted cyclopentadienyl (Cp) ring towards the Fe atom, whereas the C atom attached to the same Cp ring is slightly below this plane by -0.128 (2) Å. These deviations might result from weak agostic interactions between the two H atoms of the CH₂ group and the Fe atom.
