El Yoduro de germanio es un compuesto quím … El Yoduro de germanio es un compuesto químico de germanio y yodo. Los dos compuestos que existen con este nombre son el yoduro de germanio (II) GeI2 y el yoduro de germanio (IV) GeI4. El yoduro de Germanio (II) es un sólido cristalino que se descompone al fundirse. Su densidad específica es 5.37 y puede ser sublimado a 240 °C al vacío. El yoduro de Germanio (IV) es un sólido cristalino cuyo punto de fusión es 144 °C y su punto de ebullición es de 440 °C. Su densidad relativa es de 4.32. Es soluble en disolventes no polares como disulfuro de carbono, cloroformo o benceno.sulfuro de carbono, cloroformo o benceno.
, Germanium iodide is a chemical compound of … Germanium iodide is a chemical compound of germanium and iodine. Two such compounds exist: germanium(II) iodide, GeI2, and germanium(IV) iodide GeI4. 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. 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, CH2, are replaced with diiodogermylene groups, GeI2. 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, but hydrolyses readily.roform or benzene, but hydrolyses readily.
