The subject of the invention is derived ionic compoundsnof malononitrile in which the anionic charge isndelocalized.n n n An ionic compound of the invention comprises an anionic part associated with at least one cationic part M m + in sufficient number to ensure the electronic neutrality of the assembly. It is characterized in that M is a hydroxonium, a nitrosonium NO + , an ammonium -NH 4 + , a metal cation having the valence m, an organic cation having the valence m or an organometallic cation having the valency m, and that the anionic portion corresponds to one of the formulas R D -YC (C≡N) 2 - or ZC (C≡N) 2 - in which Z is an electron-withdrawing group, R D is an organic radical and Y is a carbonyl, a thiocarbonyl, a sulfonyl, a sulphinyl or a phosphonyl.n n n The compounds are useful in particular fornionic conduction, electronically conductive materials,ndyes and catalysis of various chemical reactions. |
