SYNTHESIS AND STRUCTURAL-ANALYSIS OF AN INFINITE LINEAR COORDINATION NETWORK FORMED BY THE SELF-ASSEMBLY OF TETRACYANOCALIX[4]ARENE LIGANDSAND SILVER CATIONS

Using the O-alkylation of the lower rim of the calix[4]arene to impose the 1,3-alternate conformation and the functionalisation of the upper rim to set-up four nitrile groups pointing in a divergent fashion, an exo-ligand capable of forming linear coordination networks was obtain ed; upon self-assembly of the latter and silver cation, a linear coord ination polymer was obtained and structurally analysed in the solid st ate by an X-ray study.
