Iron phosphide is a chemical compound of iron and phosphorus, with a formula of FeP. [1] Crystals are isolated as grey needles.

Manufacturing of iron phosphide takes place at elevated temperatures, where the elements combine directly. [1] Iron phosphide reacts with moisture and acids producing phosphine (PH3), a toxic and pyrophoric gas.

Iron phosphide is a good electric and heat conductor. [2]

Below a Néel temperature of about 119 K, FeP takes on an helimagnetic structure. [3]
