Bromine monochloride

Its molecular structure in the gas phase was determined by microwave spectroscopy; the Br-Cl bond has a length of re = 2.1360376(18) Å.

[2] Its crystal structure was determined by single crystal X-ray diffraction; the bond length in the solid state is 2.179(2) Å and the shortest intermolecular interaction is r(Cl···Br) = 3.145(2) Å.

[3] Bromine monochloride is used in analytical chemistry in determining low levels of mercury, to quantitatively oxidize mercury in the sample to Hg(II) state.

A common use of bromine monochloride is as an algaecide, fungicide, and disinfectant of industrial recirculating cooling water systems.

Addition of bromine monochloride is used in some types of Li-SO2 batteries to increase voltage and energy density.

E.g. water Instability 2: Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water. E.g. white phosphorus Special hazard OX: Oxidizer. E.g. potassium perchlorate
