A square array of metal ions from the full metallation of calix[4]resorcinarenes

Abstract

A square array of zirconium(1v) and iron(I1) ions bound to a polyoxo matrix is achieved in the metallation of calix[4]resorcinarene (R = C6H13, H) using [ Z ~( T ~-C ~H ~) ~M ~~] and [Fe(phen)(mes)~], respectively.

Resorcinarene-based cavitands as building blocks for crystal engineering

“…5) 51 with the purpose of obtaining a polymetallic functionalizable skeleton and tuning the shape and binding properties of the cavity. Back in 1996, a tetrakisIJzirconocene)calixIJ4)resorcinarene was reported by Floriani and co-workers (ZUCXEA, Fig.…”

Synthesis, characterization and antimicrobial activity of macrocylic phenoxo-bridged di- and tetra-nuclear complexes from N,N-bis[2,6-diiminomethyl-4-methyl-1-hydroxyphenyl]succinoyl/sebacoyldicarboxamides

“…Recently, considerable attention has been paid to the preparation and properties of binuclear complexes due to their potential applications in bioinorganic chemistry, material sciences and homogeneous catalysis [5,6]. Apart from their particular structural features, supramolecular species formed by self-assembly of transition metals introduced many functional properties such as luminescene [7], redox activity [8] and magnetism [9] into the structure.…”

Inclusion complexes of 18-crown-6 and (Na+⊂[2.2.2]cryptand) in [C-methylcalix[4]resorcinarene-Hn], n⊕=⊕0, 1

“…C-Methylcalix [4]resorcinarene 1 is a resorcinol-based macrocycle which commonly assumes a bowl-shaped conformation in organic media. 1 The curved architecture of such calix [4]resorcinarenes, and the phenolic groups on the upper rim, render them ideal for both the inclusion of appropriately sized and shaped species 2,3 as well as interaction with metal ions 4 or hydrogen-bonding species at the periphery. 5 A range of assemblies with defined interiors and interesting extended structures have been obtained using C-methylcalix [4]resorcinarene.…”
