Answer:

Manganese(III) fluoride

Explanation:

Since manganese is a transition metal with multiple common oxidation states, it is conventional to write its oxidation state of it in the compound in Roman numerals enclosed in parentheses. It's oxidation state is #+3# in this compound, because there are three #F# atoms (ionic charge #-1#) per one #Mn# atom.

For a binary compound, the cation is written first (with specified oxidation state in parentheses afterward) followed by the anion, which will end in -ide: Manganese(III) fluoride.
