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 (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]
