A neutral uranyl dimeric complex and remarkable extraction properties of a 1-acid 3-diethyl amide substituted calix[4]arene ligand
Abstract
The crystal structure of [(UO2)2L2] (L = 1-acid 3-diethyl amide substituted calix[4]arene) has been determined; the uranyl, lanthanide and heavy metal extraction properties of L and of a recyclable polymeric calix[4]arene based resin material are also described.
