Donat Mg is a brand name registered by the company Droga Kolinska (located in Ljubljana) which is in turn owned by Atlantic Grupa and also produces Slovenia's best known soft drink, Cockta. Today, Donat Mg is distributed in various European countries. Mineral contents The recommended amount is 500 ml per day. Because of its hyperosmolarity, Donat Mg is a natural osmotic laxative. It is classified as a saline laxative. Its effectiveness as a laxative is due to sulphate salts (magnesium sulphate or Epsom salt and sodium sulphate or Glauber’s salt) and around 1000 mg/l of magnesium. Sulphates draw water from the cells
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
