Molybdenum (III) iodide is an inorganic chemical compound of molybdenum from the group of iodides .
Extraction and presentation
Molybdenum (III) iodide can be produced by reacting molybdenum hexacarbonyl with iodine at 105 ° C
or molybdenum (V) chloride in a carbon disulfide solution with hydrogen iodide .
It is also possible to use molybdenum and an excess of iodine at 300 ° C.
properties
Molybdenum (III) iodide is a black, antiferromagnetic solid that is stable in air at room temperature. In a vacuum it decomposes from a temperature of 100 ° C into molybdenum (II) iodide and iodine. It is insoluble in polar and non-polar solvents . Molybdenum (III) iodide has a crystal structure isotypic to that of zirconium (III) iodide .
