A metal-radical hetero-tri-spin SCM with methyl–pyrazole–nitronyl nitroxide bridges

Abstract

The preparation, crystal structures, and magnetic properties of a family of hetero-tri-spin 1-D coordination polymers with formula [Ln(hfac)3Cu(hfac)2(4-NIT-MePyz)2] (Ln = Gd, 1, Tb, 2, Dy, 3; hfac = hexafluoroacetylacetonate; 4-NIT-MePyz...

Investigation and control of metallogel formation for the deposition of supramolecular nanotubes of single-chain magnets

“…However, one can note the presence of two simultaneous relaxation processes is not common for SCM systems, although already reported in the literature. [68][69][70] Moreover, Ln-NIT systems are known to generate [Ln-NIT] n chains but also [NIT-Ln-NIT] complexes. 71,72 The latter can behave as SMM with U eff and t 0 values, which could be misinterpreted as D eff and t 0 resulting in an SCM relaxation.…”

Synthesis, Structure and Magnetic Property of a New Cobalt (II) Complex Based on Pyridyl-substituted Imino Nitroxide Radical

“…Therefore, chemists pay much attention to the design of different kinds of metal-radical complex architectures with appropriate organic nitroxide radicals and coligands in the research. A large number of metal-radical complexes with various structures have been synthesized and magnetically characterized [8][9][10][11][12][13]. Meanwhile, the Cobalt(II) ion is a very effective spin carrier, however, the study of Co(II)-imino nitroxide radical complexes, particularly four-coordinated ones are rare due to a large spin-orbital coupling [14,15].…”

Ferroelastic-like transition and solvents affect the magnetism of a copper–organic radical one-dimensional coordination polymer

“…[1][2][3] Originally employed as biological markers, they were then sought as building blocks in the syntheses of magnetic materials. [4][5][6][7][8][9][10] The first success was that the revelation of long-range magnetic ordering for a purely organic compound was disclosed, which was made up of non-bonded molecules with weak supramolecular interactions. 11 It was followed by the realization of metal-organic radical magnets.…”
