✦ Synopsis

The synthesis of a new tetra(2-pyridylmethyl)amide calix[4]arene is reported. Its binding properties towards alkali and alkaline earth metals, transition metals and lanthanides have been determined along with the complexes stoichiometries. 1 H NMR investigations allowed the location of cations in the receptor to be determined. The synthesis and crystal structure of the related tetra(benzyl) derivative are also reported.
