Abstract
Abstract The newly prepared and fully characterized stibenium and bismuthenium ions [R ind MesE] + (E=Sb, Bi; R ind =dispiro[fluorene‐9,3′‐(1′,1′,7′,7′‐tetramethyl‐s‐hydrindacen‐4′‐yl)‐5′,9′′‐fluorene) were rigorously compared to the previously communicated phosphenium and arsenium ions (E=P, As) as well as the bis( m ‐terphenyl) pnictogenium ions [(2,6‐Mes 2 C 6 H 3 ) 2 E] + (E=Sb, Bi). It is demonstrated that the choice of the aryl substituents dramatically effects the molecular structures (e. g. the primary E−C bond lengths) and the electronic structures (e. g. the energy of the LUMOs).
