Ionic compounds with delocalized anionic charge, and their use as ion conducting components or as catalysts

Ionic compound corresponding to the formula

• 40
• in which:
• Mm+ is a proton or a metal cation having the valency m, chosen from ions of alkali metals, of alkaline-earth metals, of transition metals or of rare-earth metals, or an organic onium cation or an organometallic cation, 1≦m≦3;
• X1 and X2, denoted below by Xi, represent, independently of each other, S=Z3, S=Z4, P—R3 or P—R4;
• Q represents N, CR5, CCN or CSO2R5;
• Z1, Z2, Z3 and Z4, denoted below by Zi, represent, independently of each other, ═O, ═NC≡N, ═C(C═N)2, ═NS(=Z)2R6 or ═C[S(=Z)2R6]2, Z having the same meaning as Zi, it being understood that, in a segment —X-Q-X2—, not more than 3 groups Zi represent ═O;
• R1, R2, R3, R4, R5 and R6, denoted below by Ri, represent, independently of each other, Y, YO—, YS—, Y2N— or F;
• Y represents a monovalent organic radical, preferably containing from 1 to 16 carbon atoms, chosen from alkyl, alkenyl, oxaalkyl, oxaalkenyl, azaalkyl, azaalkenyl, aryl, alkylaryl or perfluoroalkyl radicals, or from the radicals obtained from the abovementioned radicals by substitution, in the chains and/or the aromatic part, with hetero atoms such as halogens, oxygen, nitrogen, sulfur or phosphorus;
• it being understood that sulfur or phosphorus are present, they can optionally be linked to substituted nitrogen or oxygen atoms, or alternatively Y is a repeating unit of a polymeric frame.
