Ferromagnetic Properties of a Trinuclear Nickel(II) Complex with a Trithiocyanurate Bridge

“…The magnetic exchange interactions, antiferromagnetic or ferromagnetic, are of interest, as the complexes can find industrial applications. [1][2][3] From both structural and magnetic aspects, binuclear copper(II) complexes have been well studied and much fewer triangular trinuclear ones have been described. In the literature we can find examples of these trinuclear complexes where the copper centers are often bridged by hydroxy groups or nitrogen heterocycles.…”

Multiple nearest-neighbor exchange model for the frustrated magnetic molecules{Mo72Fe30}andSchröder1, Prozorov2, Kögerler3 et al. 2008Phys. Rev. B

“…1,2,3,4,5 Among these diverse systems the pair of Keplerate structural type magnetic molecules abbreviated as {Mo 72 Fe 30 } and {Mo 72 Cr 30 }, each hosting a highly symmetric array of 30 exchange-coupled magnetic ions ("spin centers"), serve as highly attractive targets for the investigation of frustrated magnetic systems. In these molecules 6,7 the magnetic ions Fe III (spin s = 5/2) and Cr III (spin s = 3/2) occupy the 30 symmetric sites of an icosidodecahedron, a closed spherical structure consisting of 20 corner-sharing triangles arranged around 12 pentagons (diamagnetic polyoxomolybdate fragments).…”

MAGNETIC AND STRUCTURAL STUDY OF UNSOLVATED [Cu(acac)2], (acac= acetylacetonate)

“…This need has boosted the development of new, imaginative synthetic techniques, far away of the traditional synthetic routes. [1][2][3][4] One of the strategies used to obtain magnetic molecular compounds with heterospins has been the assembly of different paramagnetic building blocks by reaction between organic ligands and metal complexes with desired features.…”
