A new approach for the synthesis of magnetic materials based on nitroxide free radicals and inorganic coordination polymers

Synthesis, structures, and properties of two new binuclear complexes based on carboxyl-substituted nitronyl nitroxide: [M<sub>2</sub>(NITpBA)<sub>4</sub>(H<sub>2</sub>O)<sub>2</sub>] (M = Zn and Cu)

“…In an effort to bring together the two areas of research, carboxyl-substituted nitronyl nitroxide, as an important anionic ligand, was deemed favorable for the realization in reactions with metal ions. To the best of our knowledge, to prepare transition metal complexes with nitronyl nitroxide-substituted carboxylate ligands, many investigations on the scope have been recently performed, but the related reports are very scarce [5,6]. The only structurally characterized transition metal compounds are 1D-chain systems in which two nitronyl nitroxides NITpBA − are coordinated with two metal centers via one NO-group and a monodentate carboxylate group [7,8].…”

Synthesis, crystal structure, and magnetic properties of a new Fe(II) complex with reduced radical ligands

“…Therefore, chemists pay much attention to the design of different kinds of metal-radical complex architectures with appropriate organic nitronyl nitroxide radicals and coligands. A large number of metal-radical complexes with various structures have been synthesized and magnetically characterized [20][21][22][23]. However, Fe(II)-radical complexes are very scarce; to the best of our knowledge, there are only two reports on Fe(II) complexes with nitroxide radicals [24,25].…”

Synthesis, structural, and magnetic properties of a supramolecular assembly constructed from radical cations and [Au(CN)2]− anions

“…In supramolecular assemblies of radical cations with other anions, open shell anions will have magnetic interactions with radical cations in the absence of chemical bonds through space, and even the close shell anions will also influence the magnetic interactions between the adjacent radical cations in the system. Such compounds are good examples for the study of magnetic interactions through space [3][4][5][6][7][8][9][10][11][12][13][14][15].…”
