Chemical properties

Germanium(IV) iodide reacts with tetraalkyl tin at 250 °C to form R2SnI2 and R2GeI2 (R= Et, Bu, Ph).[3] It reacts with germanium and sulfur at high temperatures to produce red GeSI2 and orange Ge2S3I2.[4] It reacts with diiron nonacarbonyl in an ionic liquid ([BMIm]Cl/AlCl3) at 130 °C to obtain Ge12[Fe(CO)3]8I4.[5]

Physical properties

Germanium(IV) iodide is an orange-red crystalline solid that hydrolyzes in water. It is soluble in carbon disulfide and benzene, but less soluble in carbon tetrachloride and chloroform.[6] It begins to decompose into germanium(II) iodide and iodine above its melting point.[7] Germanium(IV) iodide crystallizes in the cubic crystal system, space group PaШаблон:Overline (space group no. 205), with the lattice parameter a = 11.89 Å. The crystal structure consists of tetrahedral GeI4 molecules.
