Molybdenum ( II) bromide is an inorganic chemical compound of molybdenum from the group consisting of bromides.

Production and representation

Molybdenum ( II) bromide may be obtained by reaction of molybdenum ( II) chloride with lithium bromide.

Also possible is the representation of the reaction of molybdenum with a bromo- nitrogen mixture at 680 ° C or by the disproportionation of molybdenum (III ) bromide in a vacuum at 600 ° C.

Properties

Molybdenum ( II) bromide is a diamagnetic, hygroscopic, yellow to brown - red powder, which is insoluble in water and acids. It is soluble in hot concentrated sulfuric acid or in warm, dilute, strong bases ( with concentrated bases decomposition takes place ) is. The addition of hydrochloric acid or hydrobromic acid to the alkaline solution leads to the Mischhalogeniden [ Mo6Br8 ] Cl4 and [ Mo6Br8 ] I4. The crystal structure of molybdenum ( II) bromide is isotypic to that of molybdenum ( II) chloride.
