Alkali−manganese(II) trifluoroacetates were synthesized, and their potential as single-source precursors for the solid-state and solution-phase synthesis of AMnF3 fluoroperovskites (A = Na, K, Rb, Cs) was demonstrated. Assembling Na2Mn2(tfa)6(tfaH), K2Mn2(tfa)6(tfaH)2·H2O, Rb2Mn2(tfa)6·H2O, and CsMn(tfa)3 (tfa = trifluoroacetate) was facilitated by the coordination flexibility of the trifluoroacetato ligand. The synthetic approach described in this investigation provides a starting point to expand the library of fluorinated single-source precursors suitable for solution-phase routes to mixed-metal fluorides.
