Abstract

A novel heteronuclear exchange-coupled complex [CrIII{(CN) FeIII-(5L}3(CN)3] containing a pentadentate blocking ligand 5L was synthesized. The X-ray structure shows that a meridional isomer applies with inequivalent FeIII centers. The complex exhibits a thermally induced spin crossover along with the exchange coupling. Mössbauer spectra indicate a spin transition between S = 1/2 and S = 5/2 states although a considerable amount of FeIII centers stays high-spin at T = 6 K. The magnetization, the magnetic susceptibility, and the Mössbauer data were fitted in one run with a spin crossover model taking into account exchange interactions among all metal centers.
