Magnetic properties of calixarene-supported metal coordination clusters

Multinuclear metal complexes have shown a unique capacity to provide interesting magnetic, chemical and electronic properties by virtue of the remarkably diverse range of structural types that they exhibit. Calix[n]arenes are now a mature synthetic platfom that provide for a diverse spatial arrangement of binding groups, making them highly suitable to use for the formation of multinuclear metal ion complexes. Increasing interest has been shown in the development and properties of magnetic materials based on calixarene macrocycles. Here, we review the magnetic properties of calixarene-supported metal clusters with emphasis on those examples exhibiting slow magnetic relaxation. (C) 2019 Elsevier B.V. All rights reserved.
