| Abstract: | AbstractMetal cations observed with tetrachloroaluminate anion provide insights into the structure and stability of reactive cations. Addition of tris(3,5-dimethylpyrazolyl)borate anion (TpMe2) to BiCl2]AlCl4] traps a bismuth(III) dication, TpMe2Bi]2+, possessing a highly electrophilic bismuth center with short coordinate Bi―N bonds. TpMe2Bi]2+ has weak interactions with the chlorides of Bi3Cl13]∞. Strong affinity of TpMe2Bi]2+ with the triflate (OTf) observed in TpMe2Bi(OTf)3]- demonstrates the high electrophilicity at bismuth. |
