| Hazard Information | Back Directory | [Chemical Properties]
In contrast to the chloride, iron(III) bromide is unstable
under these conditions. The hydrated bromide can be dehydrated in a stream of hydrogen
bromide at 400°C. Iron(II) bromide forms a layer lattice of the CdI2 type. It has a magnetic
moment,μeff= 5·71 B.M. at 295°K. It is deliquescent and very soluble in water; the pale
green hexahydrate crystallizes at room temperature, the tetrahydrate above 49°C and the
dihydrate above 83°C. A 9-hydrate forms below -29·3°C. The anhydrous salt is also
soluble in ether, ethanol and acetonitrile. | [Chemical Properties]
Yellow to dark brown lumps | [Preparation]
Iron(II) bromide can be prepared by the direct reaction of bromine or hydrogen
bromide with iron at red heat. | [General Description]
