Complexation of UO2F2 by a series of bidentate organic ligands is stud
ied. Complexes are obtained with 2,2'-bipyridyl and 1,10-phenanthrolin
e of formula UO2F2.S and with methylenebis(diphenylphosphineoxide) (A)
of formula UO2F2.2H2O.A. Suggestions are made about the structures of
the complexes and the significance of steric factors in their formati
on.
