Water-Soluble 15-Metallacrown-5 Complexes: Molecular Structures and Properties

Structural and Magnetic Properties of a {GdCu5}2 Metallacrown Dimer with a Disulfonate Linker

“…They can be easily obtained by one-pot reactions with α-substituted hydroxamic acids and consist of five repeating -[MÀ NÀ O]-fragments with an additionally coordinated central lanthanide(III) ion. [38][39][40][41] Despite the large number of reports devoted to structural studies of the features of 15-metallacrown-5 complexes and their assemblies with polycarboxylate linkers, investigations devoted to the electronic structures of these complexes remain scarce. [42][43][44][45][46] The 15-metallacrown-5 complexes are of particular interest for their magnetic properties.…”

“…Heteropolynuclear 3d–4f 15‐metallacrown‐5 complexes belong to an extensive family of metallamacrocycles. They can be easily obtained by one‐pot reactions with α‐substituted hydroxamic acids and consist of five repeating ‐[M−N−O]‐ fragments with an additionally coordinated central lanthanide(III) ion [38–41] . Despite the large number of reports devoted to structural studies of the features of 15‐metallacrown‐5 complexes and their assemblies with polycarboxylate linkers, investigations devoted to the electronic structures of these complexes remain scarce [42–46] .…”
