Magnesium iron hexahydride
Magnesium iron hexahydride is an inorganic compound with the formula Mg2FeH6. It is a green diamagnetic solid that is stable in dry air. The material is prepared by heating at mixture of powdered Mg and Fe under high pressures of hydrogen:〔J. J. Didisheim, P. Zolliker, K. Yvon, P. Fischer, J. Schefer, M. Gubelmann, A. F. Williams "Dimagnesium iron(II) hydride, Mg2FeH6, containing octahedral FeH64− anions" ''Inorganic Chemistry'' 1984, vol. 23, pp 1953–1957. .〕
:2 Mg + Fe + 3 H2 → Mg2FeH6
==Structure==
The compound is isomorphous with K2PtCl6, i.e., their connectivities are the same. The ()4− centre adopts octahedral molecular geometry with Fe-H distances of 1.56 Å. The Mg2+ centres are bound to the faces of the octahedron, with Mg-H distances of 2.38 Å. Several related compounds are known including salts of ()4−, ()4−, and ()2− anions.〔Robert Bau , Mary H. Drabnis "Structures of transition metal hydrides determined by neutron diffraction" Inorganica Chimica Acta 1997, vol. 259, 27ff.〕
