Chemical compound
Selenium dibromide is a compound made of one selenium and two bromine atoms. It is unstable. No solid form of the compound has been discovered but it is a component of the equilibria in the vapour above selenium tetrabromide (SeBr4) and in nonaqueous solutions.[1] In acetonitrile solution, selenium reacts with SeBr4 to form an equilibrium mixture containing SeBr2, Se2Br2 and Br2.[2] This covalent compound has a bent molecular geometry in the gas phase.[3]
