本人英文水平有限,望哪位高手翻譯下次段落,謝謝! The interaction between the metal cation and the axial ligand affects the magnetic behavior of the Fe(II) and Mn(II) complexes of hemiporphyrazine(半紫菜嗪). 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. |

| 金屬陽離子和軸向配體之間的相互作用影響著半紫菜嗪中Fe(Ⅱ)和Mn(Ⅱ)配合物的磁行為。有研究報(bào)道了金屬陽離子相對于大環(huán)平面的位置與卟啉及酞菁大環(huán)自旋態(tài)之間的關(guān)系。所有證據(jù)表明,如果金屬陽離子位于大環(huán)平面,其自旋態(tài)居中,若金屬陽離子位于環(huán)平面以外,將擁有高自旋態(tài)。就Fe(Ⅱ)和Mn(Ⅱ)配合物而言,他們表現(xiàn)出高自旋基態(tài)(S=2, S=5/2)。這表明,分子(如H2O或HCl)之間的相互作用拖拽Fe(Ⅱ)和Mn(Ⅱ)金屬陽離子遠(yuǎn)離半紫菜嗪平面。不過,為了確定金屬配合物的磁行為,也需要考慮許多其他因素,包括較弱的配位場和大環(huán)較低的對稱性。可從紅外光譜中觀察到半紫菜嗪中Fe(Ⅱ)和Mn(Ⅱ)配合物從高自旋態(tài)向低自旋態(tài)的轉(zhuǎn)變。 |
