Electronic structure determination of iron(II) phthalocyanine via magnetic susceptibility and Mouml;ssbauer measurements

摘要

Mouml;ssbauer and magnetic susceptibility measurements of iron(II) phthalocyanine in the temperature range between 77 and 300 K have been carried out. The crystal field parameters and the electronic structure of the Fe(II) ion have been obtained using a leasthyphen;squares fitting procedure of the dependence on the temperature of both magnetic susceptibility and quadrupole splitting. It is concluded that the ground state has major3Acharacter.
