The invention relates to ionic compounds in which the anionic charge is delocalized. A 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. M is a hydroxonium, a nitrosonium NO +, an ammonium -NH4 +, a metal cation having the valence m, an organic cation having the valence m, an organometallic cation having the valency m. The anionic charge is carried by a pentacyclic ring or tetrazapentalene derivative carrying electroattractive substituents. The compounds are useful in particular for ionically conductive materials, electronically conductive materials, dyes and catalysis of various chemical reactions. |
