Molybdenum(III) iodide is the inorganic compound with the formula MoI3.
Preparation
Molybdenum(III) iodide is created by the reaction of molybdenum hexacarbonyl with iodine gas at 105 °C (221 °F).[2]
- 2 Mo(CO)6 + 3 I2 → 2 MoI3 + 12 CO
It can also be made from molybdenum(V) chloride and a solution of hydrogen iodide in carbon disulfide.
- MoCl5 + 5 HI → MoI3 + 5 HCl + I2
A further method is direct reaction between molybdenum metal and excess iodine at 300 °C (572 °F).
- 2 Mo + 3 I2 → 2 MoI3
As molybdenum(III) iodide is the highest stable iodide of molybdenum, this is the preferred route.[1]
Properties
Molybdenum(III) iodide is a black antiferromagnetic solid that is air-stable at room temperature. In vacuum, it decomposes above 100 °C to molybdenum(II) iodide and iodine. It is insoluble in polar and non-polar solvents.[2] Its crystal structure is isotypic with zirconium(III) iodide.[3]
