Шаблон:Chembox Iron tetracarbonyl diiodide is the inorganic compound with the formula FeI2(CO)4. The molecule features four carbonyl ligands and two iodides. It is a low-spin complex of ferrous iron. As confirmed by X-ray crystallography, the compound has cis stereochemistry.[1] It is a black solid that is soluble in dichloromethane and related organic solvents.

Preparation and reactions

It is prepared by the reaction of molecular iodine with iron pentacarbonyl, following a procedure first reported by Hieber and Wirschung in 1940:[2]

Fe(CO)5 + I2 → FeI2(CO)4 + CO

Iron tetracarbonyl diiodide reacts with a variety of Lewis bases with displacement of one or two CO ligands.[3]
