WebThe reaction of Bi, BiBr 3 , and CuBr in the Lewis-acidic ionic liquid [BMIm]Br·4AlBr 3 (BMIm = 1- n -butyl-3-limidazolium) at 180 °C yielded air-sensitive, shiny black crystals of (CuBi 8 )[AlBr 4 ] 2 [Al 2 Br 7 ]. Crystals of [ M Bi 10 ][AlCl 4 ] 4 ( M = Pd, Pt) were obtained by reacting Bi, BiCl 3 , and M Cl 2 under similar conditions. The structures have been … Bismuth compounds are compounds containing the element bismuth (Bi). Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. Many of its chemical properties are similar to those of arsenic and antimony, although they are less toxic than derivatives of those lighter elements.
