Synergistic Complexes of Tributyl Phosphate and Dibutyl (Butyl) Phosphonate with Uranyl bis(β-diketonates). Synthesis,Characterisation and Molecular Structure of [UO 2 (TTA) 2 .TIBP]

Abstract

Tributyl phosphate or dibutyl (butyl) phosphonate complexes of the type [UO₂ (OO)₂.X] (OO = TTA or DBM; X = TBP, TIBP or DBBP) have been prepared and characterised by ¹H and ³¹P{¹H} NMR, IR and elemental analyses. The structure of complex [UO₂(TTA)₂.TIBP] shows that the TIBP ligand coordinates through its phosphoryl oxygen atom to the uranyl ion.
