The title compound, {(C(6)H(11)N(2))[CrCl(3)]}(n), was generated via mixing of the ionic liquid 1-ethyl-3-methyl-imidazolium chloride with CrCl(2) in ethanol. Crystals were obtained by a diffusion method. In the crystal structure, the anion forms one-dimensional chains of chloride-bridged Jahn-Teller distorted chromium(II) centers extending along the [100] direction. The imidazolium cations are positioned between these chains.
