Abstract
The structure of the title compound, [Fe(C5H5)(C10H12N2)]I, consists of a 1-(ferrocen-1-ylmethyl)-3-methylimidazolium cation which is counter-balanced by an iodide anion. The cyclopentadienyl (Cp) rings of the ferrocene unit have a slightly staggered conformation skewed from an ideal eclipsed conformation by an angle of 3.5 (6)°. The interplanar angle between the Cp and the imidazole ring is 67.94 (2)°.
