Chemical compound
From Wikipedia, the free encyclopedia
Yttrium(III) bromide is an inorganic compound with the chemical formula YBr3. It is a white solid. Anhydrous yttrium(III) bromide can be produced by reacting yttrium oxide or yttrium(III) bromide hydrate and ammonium bromide. The reaction proceeds via the intermediate (NH4)3YBr6.[3] Another method is to react yttrium carbide (YC2) and elemental bromine.[4] Yttrium(III) bromide can be reduced by yttrium metal to YBr or Y2Br3.[5] It can react with osmium to produce Y4Br4Os.[6]
