SHOW ALL QUESTIONS
Gold(III) bromide is a dark-red to black crystalline solid.[3][4][5] It has the empirical formula AuBr3, but exists as a dimer with the molecular formula Au2Br6 in which two gold atoms are bridged by two bromine atoms.[4][5][6] It is commonly referred to as gold(III) bromide, gold tribromide, and rarely but traditionally auric bromide, and sometimes as digold hexabromide. The analogous copper or silver tribromides do not exist.[7]
