  Synthesis, spectroscopic, and X-ray crystallographic characterisation of thorium(IV) and uranium(IV) malonato and substituted malonato compounds

  摘要：

  With doubly protonated piperazine or ethylenediamine as cations, eight Th(IV) malonato or substituted malonato complexes have been prepared and characterised by elemental analysis, thermal analysis, IR and C-13 CPMAS NMR spectroscopy. One polymeric U(IV) malonato complex has also been prepared and characterised by elemental analysis, thermal analysis and IR spectroscopy. (C4H12N2)(2)[Th(C3H2O4)(4)]. H2O (2), (C2H10N2)(2)[Th(C3H2O4)(4)(H2O)] (3), (C4H12N2)(2)[Th(C4H4O4)(4)]. 2H(2)O (4), (C2H10N2)(2)[Th(C5H6O4)(4)]. 5H(2)O (6) and [U(C3H2O4)(2)(H2O)(3)](n) (9) have been further characterised by single-crystal X-ray diffraction. Two types of monomeric anion structure are identified in the Th compounds: four 1,5-bidentate ligands in a distorted square antiprismatic geometry, giving coordination number (CN) 8; and four 1,5-bidentate ligands and a coordinated H2O molecule in a capped square antiprismatic geometry, giving CN 9. The U compound has a 3D polymeric structure, with U in an approximately capped square antiprismatic geometry, achieving CN 9 from two 1,5-bidentate ligands, each of which also bridges through a carbon yl oxygen to an adjacent U centre, and three H2O molecules. In the crystallographically-characterised Th compounds, the Th-O and C-O distances are correlated with the carbonyl resonance positions in the C-13 CPMAS NMR spectra, allowing prediction of structural types in the non-crystalline compounds.
