Resumen
Ion-exchange and conductimetric titration experiments suggest the existence of the PaF83− anion. Pure samples of K2PaF7 and Na3PaF8 have been prepared and analysed. The salt KPaF6 has been made, but a completely pure product could not be obtained from solution. Some observations have been made on the I.R. and n.m.r. spectra of the three complexes. Using an electrochemical method a preliminary set of values for the successive complexing constants k1–8 for the protactinium fluoro-complexes has been obtained.
