Lewis acid behavior of ReO2F3: (see abstract)

The reaction of Re2O7 with XeF6 in anhydrous HF provides a convenient route to high-purity ReO2F3. The fluoride acceptor and Lewis base properties of ReO2F3 have been investigated leading to the formation of [M][ReO2P4] [M = Li, Na, Cs, N(CH3)4], [K][Re2O4F7], [K][Re2O4F7]·2ReO2F 3, [Cs][Re3O6F10], and ReO2F3(CH3CN). The ReO2Pr, Re2O4F7^-, and Re3O6F10^- anions and the ReO2F3(CH3CN) adduct have been characterized in the solid state by Raman …
