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.
