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
Gallium manganese arsenide incorporated. At lower temperatures, around 250 °C, there is insufficient thermal energy for surface segregation to occur but still sufficient for a good quality single crystal alloy to form. In addition to the substitutional incorporation of manganese, low-temperature MBE also causes the inclusion of other impurities. The two other common impurities are interstitial manganese and arsenic antisites. The former is where the manganese atom sits between the other atoms in the zinc-blende lattice structure and the latter is where an arsenic atom occupies a gallium site. Both impurities act as double donors, removing the holes provided by the substitutional manganese,
