Reactivity of bi- and monometallic trifluoroacetates towards amorphous SiO₂.

ABSTRACT: The reactivity of alkali-manganese(II) and alkali trifluoroacetates towards amorphous SiO₂ (a-SiO₂) was studied in the solid-state. K₄Mn₂(tfa)₈, Cs₃Mn₂(tfa)₇(tfaH), KH(tfa)₂, and CsH(tfa)₂ (tfa = CF₃COO^-) were thermally decomposed under vacuum in fused quartz tubes. Three new bimetallic fluorotrifluoroacetates of formulas K₄Mn₃(tfa)₉F, Cs₄Mn₃(tfa)₉F, and K₂Mn(tfa)₃F were discovered upon thermolysis at 175 °C. K₄Mn₃(tfa)₉F and Cs₄Mn₃(tfa)₉F feature a triangular-bridged metal cluster of formula [Mn₃(
