Ytterbium (III ) bromide ( YbBr3 ) is a chemical compound of the elements of ytterbium and bromine. It forms colorless crystals.

Production and representation

Is a representation of anhydrous ytterbium (III ) bromide, by heating the hexahydrate in HBr stream does not succeed, leading to the formation of basic salts. However, it is possible from a mixture of hexahydrate with ammonium bromide ( NH4Br ) under high vacuum as the temperature rises. At 350 ° C, the substance is water-free.

Properties and Uses

Ytterbium is one of the lanthanoids and has the electron configuration [ Xe] 4f14 6s2. In its compounds it is preferably present in the oxidation state 3, and rarely in the 2 oxidation state.

By thermal decomposition of ytterbium (III ) bromide, the preparation of ytterbium ( II) bromide is carried out:
