±¾ÈËÓ¢ÎÄˮƽÓÐÏÞ£¬ÍûÄÄλ¸ßÊÖ·ÒëÏ´ζÎÂ䣬лл£¡ The interaction between the metal cation and the axial ligand affects the magnetic behavior of the Fe(II) and Mn(II) complexes of hemiporphyrazine£¨°ë×ϲËຣ©. There are reports on the relationship between the position of metal cation in relation to the macrocycle plane and the spin state of the related porphyrin and phthalocyanine macrocycles.All evidence indicates that if the metal cation lies in the macrocycle plane, the spin state of metal cation is intermediate while it will have high spin state if the metal cation lies out of the ring plane. In the case of Fe(II) and Mn(II)hp complexes, they exhibit high spin ground states (S = 2, S = 5/2). This suggests that the interaction of molecules such as H2O or HCl pulls the Fe(II) and Mn(II) metal cations away from the hemiporphyrazine plane. However, there are many additional factors have been considered in order to determine the magnetic behavior of metal complexes, including weaker ligand fields and lower symmetries of the macrocycles. The conversion from the high to low spin state in Fe(II) and Mn(II) complexes of hemiporphyrazine can be observed in their IR spectra. |
