The reaction Of Cp3Ln (Ln Pr, Nd, Sm, Gd, Dy, Ho, Er, Y, Tm, Yb; Cp cyclopentadienyl) with cyclohexanoneoxime in THF results in the formation of [CP2Ln (ONC6H10)]2 in moderate yields. The complexes are considered to be oxygen-bridged dimers on the basis of mass spectral data, and are relatively air-stable. Disproportionation on heating is observed for Ln Pr, Nd, Sm.
Cp 3 Ln(LnPr,Nd,Sm,Gd,Dy,Ho,Er,Y,Tm,Yb; Cp环戊二烯基)与环己酮肟在THF中的反应导致形成[CP 2 Ln(ONC 6 H 10)] 2处于中等产量。根据质谱数据,该配合物被认为是氧桥联的二聚体,并且是相对稳定的。对于LnPr,Nd,Sm,观察到加热时的歧化。
