Two in one: the bismuth bromido clusters in [Bi6Cp*6Br9][Bi7Br24]

Abstract

The reaction of [FeCp*(CO)2]2 in CH2Cl2 with BiBr3 in a 1:1 molar ratio gave the novel bismuth compound [Bi6Cp*6Br9][Bi7Br24] (1), which is composed of a cationic and an anionic bismuth bromido cluster: the cation is based on a hexanuclear bismuth {Bi6}-octahedron and the anion showing the first heptanuclear bismuth-bromido cluster within the class of bromido bismuthates.
