Silicon tetrabromide
Chemical compound / From Wikipedia, the free encyclopedia
Silicon tetrabromide, also known as tetrabromosilane, is the inorganic compound with the formula SiBr4.[1] This colorless liquid has a suffocating odor due to its tendency to hydrolyze with release of hydrogen bromide.[2] The general properties of silicon tetrabromide closely resemble those of the more commonly used silicon tetrachloride.[2]
