Chemical compound

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 reactingyttrium oxide or 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 withosmium to produce Y₄Br₄Os.^[6]
