title: 1-(4-Ferrocenylphen-yl)-3-methyl-imidazolium iodide monohydrate.
abstract: In the title compound, [Fe(C(5)H(5))(C(15)H(14)N(2))]I·H(2)O, the benzene and imidazolium rings are twisted by 17.26 (17) and 32.53 (19)°, respectively, with respect to the η(5)-C(5)H(4) plane of the ferrocenyl unit. The imidazolium ring is rotated by 48.81 (17)° with respect to the benzene ring. The packing is dominated by layers established by O-H⋯I, C-H⋯I and C-H⋯O contacts and propagating along the bc plane.
