Molybdenum(III) iodide is the inorganic compound with the formula MoI3.

[2] It can also be made from molybdenum(V) chloride and a solution of hydrogen iodide in carbon disulfide.

A further method is direct reaction between molybdenum metal and excess iodine at 300 °C (572 °F).

[1] Molybdenum(III) iodide is a black antiferromagnetic solid that is air-stable at room temperature.

[2] Its crystal structure is isotypic with zirconium(III) iodide.
