Abstract
Solid complexes of plutonyl ion with benzoyl (PMBP), acetyl (PMAP) and trifluoroacetyl (PMTFP) derivatives of 1-phenyl-3-methylpyrazol-S-one and various oxo donors such as dihexyl sulfoxide (DHSO), dioctyl sulf oxide (DOSO), dibutyl hexanamide (DBHA), dibutyl octanamide (DBOA) and dibutyl decanamide (DBDA) have been synthesized and characterized. An alytical data establish that sulfoxides form 1:1 adducts and have the stoichiometry PuO2 . X2 . Y (X = PMBP. PMAP and PMTFP) and Y = DHSO an d DOSO while amides form 1:2 adducts of the type PuO2X2 . 2A where A = DBHA, DBOA and DBDA. The I. R. spectra of sulfoxide and amide complex es indicate that the ligands are O-bonded. Spectrophotometric investig ations of the benzene solution of these complexes indicate a bathochro mic shift of the 831 nm peak to 848-853 nm region, which confirms the retention of PuO22+ moiety in these synergistic adducts.
