Abstract:
On chloride abstraction from chloro-bis{1,2,4-tri(tert-butyl)cyclopentadienyl}bismut(III) (2) with aluminum trichloride the salt [{C₅H₂(CMe₃)₃⁻1,2,4}₂Bi]⁺ AlCl₄⁻ (1) has been obtained in good yield. The crystal structure of 1 shows a bismocenium cation with nearly parallel η⁵ - cyclopentadienyl rings (10.2° inclination of the best planes) and only a slight bending of the Cpcₑₙₜ -Bi-Cpcₑₙₜ axis (172.9°).
