Protactinium bromo complexes

Bromofluorobenzene, formation by nuclear activation, 5 191-192 Bromofluorophosphine, 13 378-380 Bromopiotactinates, see Protactinium, bromo complexes of... [Pg.34]

It is convenient to discuss protactinium(IV) and (V) bromo and iodo complexes together since they have only been prepared by reacting together the component halides in anhydrous methyl cyanide (40, 46, 48). Thus NMe4PaBrg, NEtiPaBrg, and PhgMeAsPala are isolated (40,46) by removal of solvent in vacuo at room temperature. Hexabromo-niobates(V) and tantalates(V) have been prepared in a similar manner (46). Attempts to obtain octabromo complexes for these three elements have been unsuccessful. The orange hexabromoprotactinates(V) are... [Pg.30]
