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 numbers 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??-¿, wherein Z is an electroattractive group, R¿D? is an organic radical, and Y is a carbonyl, a thiocarbonyl, a sulphonyl, a sulphinyl, or a phosphonyl. The compounds can be used notably for ionic conducting materials, electronic conducting materials, colorants, and the catalysis of various chemical reactions.
L'invention a pour objet des composés ioniques dérivés du malononitrile dans lesquels la charge anionique est délocalisée. Un composé ionique de l'invention comprend une partie anionique associée à au moins une partie cationique Mm+ en nombre suffisant pour assurer la neutralité électronique de l'ensemble. Il est caractérisé en ce que M est un hydroxonium, un nitrosonium NO+, un ammonium -NH4+, un cation métallique ayant la valence m, un cation organique ayant la valence m ou un cation organométallique ayant la valence m, et que la partie anionique répond à l'une des formules RD-Y-C(CN)2- ou Z- C(CN)2- dans lesquelles Z est un groupe électroattracteur, RD est un radical organique et Y est un carbonyle, un thiocarbonyle, un sulfonyle, un sulfinyle ou un phosphonyle. Les composés sont utiles notamment pour les matériaux à conduction ionique, les matériaux à conduction électronique, les colorants et la catalyse de diverses réactions chimiques.
