The invention is related to ionic compounds, derivatives of malononitrile, in which the anionic load has been displaced. An ionic compound disclosed by the invention includes an anionic portion combined with at least one cationic portion M +m in sufficient number to ensure overall electronic neutrality; the compound is further comprised of M as a hydroxonium, a nitrosonium NO + , an ammonium —NH 4 +, a metallic cation with the valence m, an organic cation with the valence m, or an organometallic cation with the valence m. The anionic portion corresponds to one of the formulas R D —Y—C(C≡N) 2 − or Z-C(C≡N) 2 − in which Z is an electroattractive group, R D is an organic radical, and Y is a carbonyl, a thiocarbonyl, a sulfonyl, a sulfinyl, or a phosphonyl. The compounds can be used notably for ionic conducting materials, electronic conducting materials, colorants, and the catalysis of various chemical reactions. |
