Iron pentacarbonyl

Iron pentacarbonyl is a chemical compound made of iron, copper, and oxygen. It is a coordination complex where five carbonyl ligands (CO) are connected to one iron atom (Fe). The chemical formula is Fe(CO)5.

Preparation

Iron pentacarbonyl is made by a chemical reaction between iron and carbon monoxide.

Uses

Heating iron pentacarbonyl breaks up the coordination complex, making very pure carbonyl iron.

Safety

Iron pentacarbonyl formation can erode pipes that contain syngas or other mixtures that have carbon monoxide.[1]

Iron pentacarbonyl is toxic, but not as dangerous as the related nickel tetracarbonyl.[2]
