Epsom Salts Monorail Epsom Salts Monorail The Epsom Salts Monorail or Magnesium Monorail was a short-lived Lartigue Monorail in San Bernardino County, California, in the United States. It was built to carry epsomite (hydrated magnesium sulphate) from a deposit in the Owlshead Mountains to a siding of the Trona Railway. It ran nearly due east from Trona, for a distance of about . The monorail was opened in 1924 and closed in June 1926. Thomas Wright, a florist from Los Angeles, set-up a camp in Crystal Hills Wash in 1918 and prepared an area for salt mining, where he had previously found some
Low valent magnesium compounds Low valent magnesium compounds A number of stable low valent magnesium compounds containing a metal-metal, Mg-Mg, bond, where magnesium exhibits the formal oxidation state of +1 are known. These compounds generally have the formula LMg, where L represents a bulky ligand. The first examples of these stable magnesium(I) compounds were reported in 2007. The chemistry of Mg is dominated by the +2 oxidation state and prior to 2007 only examples of crystalline compounds with short Mg-Mg distances that may indicate an Mg-Mg bond were known, such as the ternary metal hydrides MgRuH, MgRuH, and MgIrH and magnesium diboride, Calculations had
