iron tetracarbonyl hydride FeH 2 (CO) 4, the first such compound to be synthesised (1931). [6] FeH 2 (CO) 2 [P(OPh) 3] 2. Salts of the FeH 6 4− anion, such as magnesium iron hexahydride, Mg 2 FeH 6, produced by treating mixtures of magnesium and iron powders with high pressures of H 2. Di- and polyiron hydrides, e.g. [HFe 2 (CO) 8] − and ...
Kleman and Åkerlind first produced FeH in the laboratory by heating iron to 2600 K in a King-type furnace under a thin hydrogen atmosphere. Molecular FeH can also be obtained (together with FeH 2 and other species) by vaporizing iron in an argon-hydrogen atmosphere and freezing the gas on a solid surface at about 10 K (-263 °C).
Anhydrous ferric hydroxide occurs in the nature as the exceedingly rare mineral bernalite, Fe(OH) 3 ·nH 2 O (n = 0.0–0.25). [4] [5] Iron oxyhydroxides, FeOOH, are much more common and occur naturally as structurally different minerals (polymorphs) denoted by the Greek letters α, β, γ and δ.
Magnesium iron hexahydride is an inorganic compound with the formula Mg 2 FeH 6. It is a green diamagnetic solid that is stable in dry air. The material is prepared by heating a mixture of powdered magnesium and iron under high pressures of hydrogen: [1] 2 Mg + Fe + 3 H 2 → Mg 2 FeH 6
