Synthesis and crystal structure of [(S(p) )-(2-phenyl­ferrocen­yl)meth­yl]tri­methyl­ammonium iodide di­chloro­methane monosolvate

As a follow-up to our research on the chemistry of disubstituted ferrocene derivatives, the synthesis and the structure of the title compound, [Fe(C(5)H(5))(C(15)H(19)N)]I·CH(2)Cl(2), is described. The cation mol­ecule is built up from a ferrocene disubstituted by a tri­methyl­ammonium methyl group and a phenyl ring. The asymmetric unit contains the iodide to equilibrate the charge and a disordered di­chloro­methane solvate. The disordered model results from a roughly statistical exchange (0.6/0.4) between one Cl and one H. The packing of the structure is stabilized by weak C—H⋯X (X = I, Cl), C—H⋯π(Cp) and C—Cl⋯π(phen­yl) inter­actions, building a three-dimensional network. The cation has planar chirality with S(p) (Fc) absolute configuration. The structure of the title compound is compared with related disubstituted (tri­meth­ylammonio)­methyl ferrocenes.
