The dibenzylideneacetone adducts of uranyl bis(beta-diketonates). The low temperature NMR behaviour and molecular structure of [UO2(TTA)2·DBA]
Uranyl complexes of the type [UO2(OO)2·DBA] (OO = TTA, DBM and BA) have been prepared and characterized by 1H, 19F and 13C{1H} NMR, IR spectroscopic techniques and elemental analyses. The low temperature behaviour of the complex [UO2 (TTA)2·DBA] was studied by the 19F NMR technique and its structure solved by single-crystal X-ray diffraction. The structure determination shows that the uranium atom has pentagonal-bipyramidal geometry with the four oxygen atoms of TTA and one oxygen atom of DBA lying on the basal plane and two uranyl oxygen atoms occupy the apices.
