SYNTHESES AND STRUCTURE, PROPERTY STUDY ON Ln(III) - Na(I) COMPLEXES OF 1,1,1-TRIFLUORO-3-(2-THENOY)ACETONE LIGAND

Abstract

The heterometallic Na(I)–Y(III)/La(III)/Lu(III) β-diketonate complexes were synthesized and structurally
characterized by MS, IR and NMR spectroscopies. The results confirmed that the central rare earth ion
is bonded to four 1,1,1-trifluoro-3-(2-thenoy)acetone (TTA) ligands through oxygen atoms of β-diketone
fragments. The anionic complex ion is then charge balanced by sodium cation to form polymeric array
in solid state.
