Substituted biurets as uranophilic ligands: a facile DMSO-induced conversion of a 1:1 into a 2:1 uranyl-ligand complex
摘要:
1,5-Bis[6-(1-ethoxycarbonyl-3-thioureido)-2-pyridindiyl]biuret and uranyl acetate gave a crystalline 1:1 uranyl-ligand complex which, on crystallization from DMSO, underwent rearrangement to a crystalline 2:1 uranyl-ligand complex and a stoichiometric amount of the uncomplexed ligand. Spectral characteristics of these ligands and their uranyl complexes together with single crystal X-ray data for the uranyl-ligand complexes are described.
