Germanium(IV) iodide reacts with tetraalkyl tin at 250 °C to form R 2 SnI 2 and R 2 GeI 2 (R= Et, Bu, Ph). [5] It reacts with germanium and sulfur at high temperatures to produce red GeSI 2 and orange Ge 2 S 3 I 2. [6] It reacts with diiron nonacarbonyl in an ionic liquid ([BMIm]Cl/AlCl 3) at 130 °C to obtain Ge 12 [Fe(CO) 3] 8 I 4. [7]
In addition to the ability of germanium to exhibit 4, 5 or 6 coordination, the greater length of the Ge–O bond in the {GeO 4} tetrahedral unit compared to Si–O in {SiO 4} and the narrower Ge–O–Ge angle (130°–140°) between corner shared tetrahedra allow for unusual framework structures. [13]
