Synthesis and Structure of Mono-, Di-, and Trinuclear Fluorotriarylbismuthonium Cations.

ABSTRACT: A series of cationic fluorotriarylbismuthonium salts bearing differently substituted aryl groups (Ar = 9,9-Me₂-9H-xanthene, Ph, Mes, and 3,5-tBu-C₆H₃) have been synthesized and characterized. While the presence of simple phenyl substituents around the Bi center results in a polymeric structure with three Bi centers in the repeating monomer, substituents at the ortho- and meta-positions lead to cationic mono- and dinuclear fluorobismuthonium complexes, respectively. Preparation of all compounds is accomplished by fluoride abstraction from the parent triaryl Bi(V) difluorides using NaBAr^F (BAr^{F -} = B[C₆H₃-3,5-(CF₃)₂]₄ ^-). Structural paramete
