Eleven novel ligands having picolinamide or thiopicolinamide bindinggroups at the upper or lowerrim of calix[4]-, calix[6]- and calix[8]arenes have been synthesised. The conformational properties of some of these ligands were studied in solution by means of NMR spectroscopy and in the solid state by X-ray diffraction. Their ability to extract AmIII or EuIII from water to NPHE (o-nitrophenyl hexyl
