The most precisely characterised FeH 2 L 4 complex as of 2003 is FeH 2 (CO) 2 [P(OPh) 3] 2. Complexes can also contain FeH 2 with hydrogen molecules as a ligand. Those with one or two molecules of hydrogen are unstable, but FeH 2 (H 2) 3 is stable and can be produced by the evaporation of iron into hydrogen gas. [6]
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 ...
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). The compound can be detected by infrared spectroscopy , and about half of it disappears when the sample is briefly warmed to 30 K. [ 15 ] A variant ...
