Magnesium chloride salts is rare in healthy individuals with a normal diet, because excess magnesium is readily excreted in urine by the kidneys. A few cases of oral magnesium toxicity have been described in persons with normal renal function ingesting large amounts of magnesium salts, but it is rare. If a large amount of magnesium chloride is eaten, it will have effects similar to magnesium sulfate, causing diarrhea, although the sulfate also contributes to the laxative effect in magnesium sulfate, so the effect from the chloride is not as severe. Chloride (Cl) and magnesium (Mg) are both essential nutrients important for normal
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]
