Germanium(IV) Bromide
Germanium tetrabromide is an inorganic compound with the formula GeBr4. It can be formed by reacting solid germanium and gaseous bromine. :Ge + 2Br2 -> GeBr4 From this reaction, GeBr4 has a heat of formation of 83.3 kcal/mol. The compound is liquid at 25 °C, and forms an interlocking liquid structure. 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. References

Tin(IV) Iodide
Tin(IV) iodide, also known as stannic iodide, is the chemical compound with the formula SnI4. This tetrahedral molecule crystallizes as a bright orange solid that dissolves readily in nonpolar solvents such as benzene. The compound is usually prepared by the reaction of iodine and tin: : Sn + 2 I2 → SnI4 The compound hydrolyses in water. In aqueous hydroiodic acid, it reacts to form a rare example of a hexaiodometallate: : SnI4 + 2 I− → nI6sup>2− See also *Tin(II) iodide *Tin(IV) chloride Tin(IV) chloride, also known as tin tetrachloride or stannic chloride, is an inorganic compound with the formula Sn Cl4.
