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

[edit]

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]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
