摘要：

The organic alloy, CoxNi1- xPc(AsF6)(0.5) (0 < x < 1), was prepared and characterized by elementary analysis (EPMA), X-ray diffraction, ESR, magnetic susceptibility, Raman spectroscopy and reflection spectroscopy. These experiments show that mixed crystals are formed for a wide range of x although CoPc(AsF6)(0.5) is not exactly isomorphous to NiPc(AsF6)(0.5). The mixing on a molecular level is proved by the x dependence of the ESR and Raman spectra over the whole range of x. Based on these results combined with the reflectivity spectra, we propose a model for the energy band near the Fermi level including the 3d bands. This band model explains the differences in the magnetic and optical properties between CoPc(AsF6)(0.5) and NiPc(AsF6)(0.5).
