Abstract

A variety of Lewis bases react with uranyl salts in ethyl acetate to give yellow crystalline complex compounds in which U(VI) has different coordination numbers according to the type and size of the ligand used.

No evidence has been obtained for the formation of any complexes between uranyl salts and some organic phosphorus ligands.

Infrared spectra, thermal stability and conductivity of the soluble adducts obtained have been discussed.
