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
Symbol (chemistry) (see Chemical elements in East Asian languages). However, Latin symbols are also used, especially in formulas. A list of current, dated, as well as proposed and historical signs and symbols is included here with its signification. Also given is each element's atomic number, atomic weight or the atomic mass of the most stable isotope, group and period numbers on the periodic table, and etymology of the symbol. Hazard pictographs are another type of symbols used in chemistry. Antimatter atoms are denoted by a bar above the symbol for their matter counterpart, so e.g. H is the symbol for antihydrogen. The
