Neodymium (II) bromide is an inorganic chemical compound of neodymium from the group of bromides .

presentation

Neodymium (II) bromide can be obtained by reducing neodymium (III) bromide with neodymium in a vacuum at 800 to 900 ° C.

${\displaystyle {\ce {Nd + 2 NdBr3 -> 3 NdBr2}}}$

properties

Neodymium (II) bromide is a dark green solid. The connection is extremely hygroscopic and can only be stored and handled under carefully dried protective gas or in a high vacuum. In air or in contact with water, it changes into hydrates when moisture is absorbed , but these are unstable and more or less quickly turn into oxide bromides with evolution of hydrogen . The compound has a crystal structure of lead (II) chloride type.
