Seven
protactinium(V) fluoride compounds have been synthesized, and their
crystal structures and Raman spectra are reported. (NH4)2PaF7, K2PaF7, Rb2PaF7, and Cs2PaF7 were found
to crystallize in the monoclinic space group P21/c for the ammonium compound and C2/c for the K+-, Rb+-, and Cs+-containing compounds, with nine-coordinate
Pa forming infinite chains through fluorine bridges. Na3PaF8 crystallizes in the tetragonal space group I4/mmm with eight-coordinate Pa in tetragonal
geometry, while tetramethylammonium fluoroprotactinate shows two different
structures: (Me4N)2(H3O)PaF8, an eight-coordinate molecular compound crystallizing in the monoclinic
space group C2/c, and (Me4N)PaF6, an eight-coordinate Pa compound forming infinite
chains and crystallizing in the orthorhombic space group Pnnm. A comparison of solid- and solution-state Raman data indicates
that the PaF8– anion could be the predominant
Pa(V) complex in concentrated solutions of aqueous HF.
