Magnesium sulfate (medical use) solution. In the United Kingdom 4 ml of 20% solution costs the NHS about 10.23 pounds. In the United States a course of medication typically costs less than $25. Magnesium sulfate is the primary treatment and preventative measure in women with eclampsia. It lowers systolic blood pressure while maintaining diastolic blood pressure, thus leaving blood flow to the fetus uncompromised. Magnesium sulphate was once used as a tocolytic, but meta-analyses have failed to support it as an anti-contraction medication. Usage for prolonged periods (more than five to seven days) may result in health problems for the baby. In those at
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]
