Magnesium sulfate (medical use) ionic strength prevents some of the temporary skin wrinkling (partial maceration) which is caused by prolonged immersion of extremities in pure water. Magnesium and sulfate ions are naturally present in some mineral waters. The claimed health benefits of Epsom Salt baths have not been proven. A magnesium sulphate paste is also available which is claimed to be useful for small boils or localised infections. The standard British Pharmacopoeia composition is dried Magnesium Sulfate 47.76 % w/w, Phenol 0.49 % w/w. and glycerol (E422). Magnesium sulfate has been used as an experimental treatment of Irukandji syndrome caused by envenomation by certain
Magnesium iron hexahydride Magnesium iron hexahydride Magnesium iron hexahydride is an inorganic compound with the formula MgFeH. 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: The compound is isomorphous with KPtCl, i.e., their connectivities and structures are the same. The [FeH] centre adopts octahedral molecular geometry with Fe-H distances of 1.56 Å. The Mg 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 [RuH], [OsH], and [PtH]
