The present invention relates to sulphur-free transition metal-isocyanate-based ionic liquids, a method for the production thereof and the usage thereof. The sulphur-free transition metal-isocyanate-based ionic liquids have the general formula (I), wherein M II is a bivalent metal cation selected from manganese 2+, nicke l2+ and cobalt 2+ ; d means one or two; I means one or two; and A is selected from quaternary ammonium cations, quaternary phosphonium cations, imidazolium cations, N, N'-(CH 2)n- diimidazolium cations, pyridinium cations, N, N'-(CH 2)n- dipyridinium cations, pyrrolidinium and bipyridinium cations, wherein n is a whole number between 1 and 5 and wherein d, A and I are selected such that the charge 2+ results overall for A d+ n i . |
