Reaction of GeF 4 with fluoride sources produces GeF 5 − anions with octahedral coordination around Ge atom due to polymerization. [6] The structural characterization of a discrete trigonal bipyramidal GeF 5 − anion was achieved by a "naked" fluoride reagent 1,3-bis(2,6-diisopropylphenyl)imidazolium fluoride.
Under normal conditions GeI 4 is a solid, GeF 4 a gas and the others volatile liquids. For example, germanium tetrachloride, GeCl 4, is obtained as a colorless fuming liquid boiling at 83.1 °C by heating the metal with chlorine. [4] All the tetrahalides are readily hydrolyzed to hydrated germanium dioxide. [4]
A notable derivative of GeCl 4 is germanium dioxide.In the manufacture of optical fibers, silicon tetrachloride, SiCl 4, and germanium tetrachloride, GeCl 4, are introduced with oxygen into a hollow glass preform, which is carefully heated to allow for oxidation of the reagents to their respective oxides and formation of a glass mixture.
Potassium hexafluoroantimonate can be prepared by reacting potassium pyroantimonate K 2 H 2 Sb 2 O 7 with hydrogen fluoride or by treating the product of the reaction of a mixture of solid antimony(III) oxide and potassium hydroxide with hydrogen peroxide solution (30%) with hydrochloric acid (48%).

Lithium hexafluorogermanate is the inorganic compound with the formula Li 2 GeF 6. It forms a solid off-white deliquescent powder. When exposed to moisture, it easily hydrolyses to release hydrogen fluoride and germanium tetrafluoride gases.
