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
Methylcyclopentadienyl manganese tricarbonyl combustion in gasoline, MMT is classified as an acute toxicant by the oral, dermal, and inhalation routes of exposure under the European Union's Classification, Labeling and Packaging Regulation (EC/1272/2008), implementing the Global Harmonized System (GHS) of Classification and Labeling. The US ATSDR (Agency for Toxic Substances and Disease Registry) notes that MMT is very unstable in light and degrades to a mixture of less harmful substances and inorganic manganese in less than 2 minutes. Therefore, human exposure to MMT prior to combustion in gasoline would not likely occur at significant levels. Regarding occupational exposure to the raw concentrated chemical prior
