Manganese(III) fluoride Manganese(III) fluoride Manganese(III) fluoride (also known as Manganese trifluoride) is the inorganic compound with the formula MnF. This red/purplish solid is useful for converting hydrocarbons into fluorocarbons, i.e., it is a fluorination agent. It forms a hydrate and many derivatives. MnF can be prepared by treating a solution of MnF in hydrogen fluoride with fluorine: It can also be prepared by the reaction of elemental fluorine with a manganese(II) halide at ~250 °C. Like vanadium(III) fluoride, MnF features octahedral metal centers with the same average M-F bond distances. In the Mn compound, however, is distorted (and hence a monoclinic unit
Manganese large consumer of manganese ores. Scheele and other chemists were aware that manganese dioxide contained a new element, but they were not able to isolate it. Johan Gottlieb Gahn was the first to isolate an impure sample of manganese metal in 1774, by reducing the dioxide with carbon. The manganese content of some iron ores used in Greece led to speculations that steel produced from that ore contains additional manganese, making the Spartan steel exceptionally hard. Around the beginning of the 19th century, manganese was used in steelmaking and several patents were granted. In 1816, it was documented that iron
