| 摘 要： | 以199Sn和23Na核磁共振研究了Na4Sn9-乙二胺体系中加入M(acacen)(M=Cu2+,Ni2+)和Ln(fod)3(Ln=Pr3+,Yb3+,Eu3+)后的化学位移和偶合常数。结果表明,假接触和体积磁化率的变化是引起化学位移变化的主要原因,而Fermi接触的贡献可以忽略。

| Abstract: | In the present work the interaction between the Na4Sn9 Zintl alloy extract in en and complexes M(acacen)(M = Cu,Ni) as well as Ln(fod)3(Ln= Pr,Yb,Eu) has been investigated by multinuclear magnetic resonance. The interpretation of the findings is discussed in terms of the NMR theory of paramagnetic ions and in relation to the magnetic properties of the complexes. It is concluded that the chemical shifts of Sn94- arise predominantly from pseudo-contact interaction and the change in volume susceptibility, while for Na+, only the effect of susceptibility is dominant. |
