| The magnetic properties of a valence delocalized mixed valent Fe(II)-Fe(III) complex have been investigated. On the basis of magnetic susceptibility measurements and NIR absorption spectroscopy the double exchange parameter was determined to B = 940 cm-1 while for the isotropic exchange interaction an antiferromagnetic contribution of J = -100 cm-1 was obtained. The results were further discussed with regard to vibronic interaction. For the vibronic-interaction parameter lambda only an upper bound of 2500 cm-1 could be given. |
