Yttrium(III) bromideis an inorganic compound with the chemical formula YBr3.It is a white solid. Anhydrous yttrium(III) bromide can be produced by reactingyttrium oxideor yttrium(III) bromide hydrate andammonium bromide.The reaction proceeds via the intermediate (NH4)3YBr6.[3]Another method is to reactyttrium carbide(YC2) and elementalbromine.[4]Yttrium(III) bromide can be reduced by yttrium metal to YBr or Y2Br3.[5]It can react withosmiumto produce Y4Br4Os.[6]
