title: Bismuthenium-pnictonium dications [R'BiPnR(3)](2+) (Pn = As, Sb) containing carbenoid bismuth centers and rare Bi-Sb bonds.
abstract: Arsine and stibine ligands stabilize bismuthenium cations and bismuthetidinium dications to give compounds containing As-Bi bonds and Sb-Bi bonds. The first enium-onium bonding environments in dications of the form [R'BiPnR(3)](2+) (Pn = As, Sb) contain the first definitive examples of carbenoid bismuth centers.
