Manganese Acetylacetonate is a Manganese source that is soluble in organic solvents as an organometallic compound (also known as metalorganic, organo-inorganic and metallo-organic compounds). The high purity acetylacetonate anion complexes by bonding each oxygen atom to the metallic cation to form a chelate ring.Because of this property, Manganese Acetylacetonate is commonly used in various catalysts and catalytic reagents for organic synthesis. It is generally immediately available in most volumes. Ultra high purity and high purity forms may be considered. Manganese Acetylacetonate is one of numerous organo-metallic compounds (also known as metalorganic, organo-inorganic and metallo-organic compounds) sold by American Elements under the tradename AE Organo-Metallics™ for uses requiring non-aqueous solubility such as recent solar energy and water treatment applications. Similar results can sometimes also be achieved with Nanoparticles (also see Nanotechnology and Quantum Dots) and by thin film deposition. Note American Elements additionally supplies many materials as solutions. The numerous commercial applications for Manganese include steel production to remove sulfur and oxygen, the colorant in natural amethyst stones and is used in glass and ceramics to also create the amethyst color.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Manganese is a Block D, Group 7, Period 4 element. The number of electrons in each of Manganese's shells is 2, 8, 13, 2 and its electronic configuration is [Ar] 3d5 4s2. In its elemental form manganese's CAS number is 7439-96-5. The manganese atom has a radius of 136.7.pm and it's Van der Waals radius is 200.pm. Manganese in excess is toxic, in particular the inhalation of manganese in powder or dust form. Manganese metal is a key component of aluminumalloys. Manganese oxide is used in dry cell batteries. Manganese is used in steel production to remove sulfur and oxygen. Manganese is the colorant in natural amethyst stones and is used in glass and ceramics to also create the amethyst color. It is used like the element cerium to "decolorize" glass by offsetting the green from impurities of ferric ions. Permanganate is a powerful oxidizing agent and is used in medicine. It is added as a nutritional supplement for both human and animal consumption. Recently, the oxide in the form of various perovskite structures have demonstrated applications in oxygen generation and solid oxide fuel cells. Manganese was first discovered by Johann Gahn in 1774. The name Manganese originates from the Latin word mangnes meaning magnet. See Manganese research below.
