Germanic Iodide, GeI₄

Germanic Iodide, GeI₄, is formed by the union of its elements, or by the interaction of germanic chloride and potassium iodide. It is an orange solid, which melts at 144° C. and boils above 300° C. Its vapour density at 440° C. is 20.46 (air = 1) or 294.6 (H = 1), theory for GeI₄ requiring 20.0 (air = 1) or 288.0 (H = 1). At a somewhat higher temperature the vapour begins to dissociate. The solid iodide deliquesces in the air and then gradually loses iodine and absorbs oxygen, so passing into the dioxide.
