Germanium iodides are inorganic compound with the formula GeIx. Two such compounds exist: germanium(II) iodide, Шаблон:Chem2, and germanium(IV) iodide Шаблон:Chem2.[1]

Germanium(II) iodide is an orange-yellow crystalline solid which decomposes on melting. Its specific density is 5.37 and it can be sublimed at 240 °C in a vacuum. It can be prepared by reducing germanium(IV) iodide with aqueous hypophosphorous acid in the presence of hydroiodic acid.[2] It is oxidised by a solution of potassium iodide in hydrochloric acid to germanium(IV) iodide. It reacts with acetylene at 140 °C to form an analogue of cyclohexa-1,4-diene in which the methylene groups, Шаблон:Chem2, are replaced with diiodogermylene groups, Шаблон:Chem2.[3]

Germanium(IV) iodide is an orange-red crystalline solid with melting point 144 °C and boiling point 440 °C (with decomposition). Its specific density is 4.32. It is soluble in non-polar solvents like carbon disulfide, chloroform or benzene,[2] but hydrolyses readily.[3]

Mixed anion compound germanide iodides are also known.
