The syntheses, structures and magnetic properties of the series of dimeric organolanthanide(III) amides [Cp2Ln2-NH-4,6-Me2pm}]2 [Ln = Nd (1), Gd (2), Dy (3), Yb (4) and pm = pyrimidine], which are formed from the deprotonation of 2-amino-4,6-dimethylpyrimidine by the corresponding lanthanide tris-cyclopentadienide, are reported. The synthesis and structure of [Cp2Yb(2-NH-4-MeO-6-MeOpm)(2)(mu3-O)(YbCp)]
系列二聚有机镧系元素(Cp2Ln 2-NH-4,6-Me2pm}] 2 [Ln = Nd(1),Gd(2),Dy(3),报道了Yb(4)和pm =嘧啶],它们是由2-氨基-4,6-二甲基嘧啶被相应的镧系元素三环戊二烯去质子化而形成的。[Cp2Yb(2-NH-4-MeO-6-MeOpm)(2)(mu3-O)(YbCp)](5)的合成和结构是在类似的质子化反应中但在不定水存在下形成的,也有报道。
