Think positive, keep the anions away: Hitherto unknown mono- and dications of the type [XE(μ-NTerE)]+ and [E2(μ-NTer)2]2+ (E=Sb, Bi; X=Cl, I) were studied and fully characterized for the first time. Salts bearing these highly reactive cations can be obtained from terphenyl-substituted cyclo-dipnictadiazanes [XE(μ-NR)]2 by halide abstraction or triflate substitution.
