Spin crossover in a tetranuclear Cr(III)-Fe(III)3 complex
2004
A novel heteronuclear exchange-coupled complex [Cr I I I {(CN)Fe I I I -( 5 L)} 3 (CN) 3 ] containing a pentadentate blocking ligand 5 L was synthesized. The X-ray structure shows that a meridional isomer applies with inequivalent Fe I I I centers. The complex exhibits a thermally induced spin crossover along with the exchange coupling. Mossbauer spectra indicate a spin transition between S = ½ and S = 5/2 states although a considerable amount of Fe I I I centers stays high-spin at T = 6 K. The magnetization, the magnetic susceptibility, and the Mossbauer data were fitted in one run with a spin crossover model taking into account exchange interactions among all metal centers.
Iron(III) bis(pyrazol-1-yl)acetate based decanuclear metallacycles: synthesis, structure, magnetic properties and DFT calculations
2016
The synthesis, structural aspects, magnetic interpretation and theoretical rationalizations for a new member of the ferric wheel family, a decanuclear iron(III) complex with the formula [Fe10(bdtbpza)10(μ2-OCH3)20] (1), featuring the N,N,O tridentate bis(3,5-di-tert-butylpyrazol-1-yl)acetate ligand, are reported. The influence of the steric effect on both the core geometry and coordination mode is observed. Temperature dependent (2.0–300 K range) magnetic susceptibility studies carried out on complexes 1 established unequivocally antiferromagnetic (AF) interactions between high-spin iron(III) centers (S = 5/2), leading to a ground state S = 0. The mechanism of AF intramolecular coupling was…
Spin crossover in mononuclear and binuclear iron(III) complexes with pentadentate Schiff-base ligands
2000
Abstract A series of mononuclear hexacoordinate iron(III) complexes, [Fe( 5 L )(py)]BPh 4 , and binuclear hexacoordinate iron(III) complexes, [( 5 L )Fe(μ 2 -bpy)Fe( 5 L )](BPh 4 ) 2 , has been prepared and their magnetic properties were investigated; the pentadentate ligands were derivatives of 5 L =saldptn=N,N′-bis(2-hydroxybenzyliden)-1,7-diamino-4-azaheptane. Temperature variation of the effective magnetic moment for them shows that a spin transition from the low-spin to the high-spin state occurs. The magnetic data were fitted to an Ising-like model appropriate for the mono- and binuclear systems.
