Uranyl dimethylmalonato complexes with different metal to ligand ratios and connectivity, 1:2 monomeric, dimeric and 2:3, 3:4 infinite chain structures have been prepared and characterised by elemental analysis, thermal analysis, IR and 13 C CPMAS NMR spectroscopy, and X-ray crystallography. The different structural types are isolated by the use of different counter-cations. Two new kinds...
The reaction of aliphatic diamine with malonic or substituted malonic acid and uranyl nitrate in the ratio 2:2:1 in aqueous media leads in most cases to one predominant product, usually with a metal-ligand ratio of 1:2, but in a few cases it leads to oligomers with metal-ligand ratios of 2:3, 3:4 and 3:5. The crystalline products are salts with diprotonated diamines as cations, but crystals can also...
