Abstract: The salt (ferrocenylmethyl)trimethylammonium iodide, [Fe(C₅H₅)(C₉H₁₅N)]I, is used in an established procedure to attach ferrocenylmethyl frameworks to secondary amines. The title salt, [Fe(C₅H₅)(C₉H₁₅N)]I₃, obtained by diffusion of Et₂O vapour into a CH₂Cl₂ solution containing equimolar [Fe(C₅H₅)(C₉H₁₅N)]I and I₂, shows the expected cation balanced by an asymmetric but isolated triiodide counteranion [I-I  = 3.0006  (4) and 2.8728  (4)  Å].
