What is Uranyl ion complexes with long chain aminoalcoholbis(phenolate) [O,N,O,O′] donor ligands about?

The reaction between uranyl nitrate hexahydrate and phenolic ligand precursor [(N,N-bis(2-hydroxy-3,5-dimethylbenzyl) 3) and the ligand [(N,N-bis(2-hydroxy-5-tert-butyl-3-methylbenzyl)-5-amino-1-pentanol) AE HCl], H 3 L4 AE HCl, leads to a uranyl complex with a formula [UO 2 (H 2 L4) 2 ] AE 2CH 3 CN (4). The ligand [(N,N-bis(2-hydroxy-5tert-butyl-3-methylbenzyl)-6-amino-1-hexanol) AE HCl], H 3 L5 AE HCl, leads to a uranyl complex with a formula [UO 2 (H 2 L5) 2 ] AE 4toluene (5). The complexes 1-5 are obtained using a molar ratio of 1:2 (U to L) in the presence of a base (triethylamine). The molecular structures of 1a, 1b, 3, 4 and 5 were verified by X-ray crystallography. All complexes are neutral zwitterions and have similar centrosymmetric, mononuclear, distorted octahedral uranyl structures with the four coordinating phenoxo ligands in an equatorial plane. In uranyl ion extraction studies from water to dichloromethane with ligands H 3 L1 AE HCl-H 3 L5 AE HCl, ligands H 3 L1 AE HCl, H 3 L4 AE HCl and H 3 L5 AE HCl are the most effective ones.
