本文报道了两种镝与氨基取代的双金属配体L-1的配合物[(C_5 H_4 Me)(2)Dy(L-1)](3)和[(L-1)Dy-(μ-Cl)(3){Li(tmeda)}](2)(4)。3和4的晶体学研究表明,侧基氨基影响的构象和配体的hapticity。电子结构的计算表明,L-1有很强的影响,在3和4的地面Kramers双峰的主磁轴的方向。
Two dysprosium complexes, [(C5H4Me)(2)Dy(L-1)] (3) and [(L-1)Dy-(mu-Cl)(3){Li(tmeda)}](2) (4), with amino-functionalized pentadienyl ligands L-1 are described. Crystallographic studies of 3 and 4 show that the pendant amino group influences the pentadienyl conformation and the ligand hapticity. Electronic structure calculations reveal that L-1 has a strong influence on the orientation of the main magnetic axis of the ground Kramers doublets in 3 and 4.
