Caesium enneabromodibismuthate is an inorganic compound with the formula Cs3Bi2Br9. It is one of the coordination complexes formed by caesium, bismuth and bromine.[1] At room temperature, it is trigonal (P3m1) and it undergoes phase transformation to monoclinic phase (C12/c1) when the temperature is below 96 K.[2]
Preparation
Traditionally, it can be synthesized from a hydrobromic acid solution of stoichiometric amounts of
1-octadecene at 170 °C using caesium oleate and bismuth(III) bromide as precursors.[6]
