Preparation
Molybdenum(III) bromide is produced by the reaction of elemental molybdenum and bromine at 350 °C (662 °F).[1]
It can also be prepared from the reduction of molybdenum(IV) bromide with molybdenum metal, hydrogen gas, or a hydrocarbon.[2]
It has a structure consisting of infinite chains of face-sharing octahedra with alternatingly short and long Mo-Mo contacts. The same structure is adopted by the tribromides of ruthenium and technetium.[3][4] In contrast, in the high temperature phase of titanium(III) iodide, the Ti---Ti separation is invariant.
