Abstract

A unique pentanuclear bismuth(III) zwitterionic thiolate complex, [Bi5(Tab)18](PF6)7(NO3)8]·6MeCN [1; Tab = 4-(trimethylammonio)benzenethiolato], was obtained from the reaction of Bi(NO3)3 with TabHPF6 in a 1:4 molar ratio in MeCN/MeOH in the presence of Et3N and structurally characterized. Single-crystal X-ray diffraction revealed that 1 consists of an unprecedented linear [Bi5(Tab)18]15+ cation, and both [PF6] and [NO3] anions in the crystal cooperatively work as anionic templates to form interesting anionic honeycomb-like cavities for encapsulating the [Bi5(Tab)18]15+cations.(© Wiley-VCH Verlag GmbH & Co.
