Germanium tetrabromide is the inorganic compound with the formula GeBr4. It is a colorless solid that melts near room temperature. It can be formed by treating solid germanium with bromine, or by treating a germanium-copper mixture with bromine:[2]
- Ge + Br2 → GeBr4
From this reaction, GeBr4 has a heat of formation of 83.3 kcal/mol.[3]
The compound is liquid at 25 °C, and forms an interlocking liquid structure.[4] From room temperature down to −60 °C the structure takes on a cubic α form, whereas at lower temperatures it takes on a monoclinic β form.
