Yj. Zhang et al., STRUCTURAL STUDIES ON MONOMERIC AND DIMERIC URANYL BIS(DIMETHYLMALONATO) COMPLEXES, Journal of alloys and compounds, 271, 1998, pp. 139-143
The use of tetramethylpropanediammonium (2+) or hexaamminecobalt (III)
as counter cations allowed the preparation of monomeric or dimeric ur
anyl bis(dimethylmalonato) complexes, respectively, which were charact
erised by solid-state C-13 NMR and X-ray crystallography. These two st
ructures are different from the monomeric and dimeric structures we re
ported earlier with unsubstituted malonate as ligand [4]. (C) 1998 Els
