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

Abstract

The reaction of [FeCp * (CO) 2 ] 2 in CH 2 Cl 2 with BiBr 3 in a 1:1 molar ratio gave the novel bismuth compound [Bi 6 Cp * 6 Br 9 ][Bi 7 Br 24 ] (1), which is composed of a cationic and an anionic bismuth bromido cluster: the cation is based on a hexanuclear bismuth {Bi 6 }-octahedron and the anion showing the first heptanuclear bismuth-bromido cluster within the class of bromido bismuthates.
