The invention relates to ionic compounds in which the anionic load has been delocalized. A compound disclosed by the invention includes an anionic portion combined with at least one cationic portion Mm+ in sufficient numbers to ensure overall electronic neutrality; the compound is further comprised of M as a hydroxonium, a nitrosonium NO+, an ammonium —NH4+, a metallic cation with the valence m, an organic cation with the valence m, or an organometallic cation with the valence m. The anionic load is carried by a pentacyclical nucleus of tetrazapentalene derivative bearing electroattractive substituents. The compounds can be used notably for ionic conducting materials, electronic conducting materials, colorant, and the catalysis of various chemical reactions.
