Synthesis and characterization of complexes of UO2(II) and Th(IV) of bis-schiff bases derived from furoylpyrazolone

Four new complexes of UO2(II) and Th(W) with bis-Schiff bases, derived from N,N'-bis[(I-phenyl-3-methyl-5-oxo-4-pyrazolinyl)-alpha-furylmethylidyne]-1,2-propylenediimine [1,2-BPMOPFP-H-2] and N,N'-bis[(I-phenyl-3-methyl-5-oxo-4-pyrazolinyl)-alpha-furylmethylidyne]-1,3-propylenediimine [1,3-BPMOPFP-H-2], were synthesized and characterized by elemental analysis, IR, UV, (HNMR)-H-1 spectroscopy, and molar conductivity. The general formula of the complexes was confirmed to be [UO2(BPMOPFP)], [Th(BPMOPFP)(NO3)]NO3. A possible structure for the complexes have been proposed.
