摘要：

The molecular structures of [M(OTf)(2)(hmpa)(4)]OTf . CHCl3 (OTf=OSO2CF3; M=Y, Ce, Pr, Nd, Sm, Eu, Gd, To, Dy, Ho, Er, Tm, Yb, Lu), [Sc(OTf)(2)(hmpa)(4)]OTf, and [La(eta(2)-OTf)(OTf)(hmpa)(4)]OTf . CHCl3 were accurately determined by single crystal X-ray analyses. Tetrad effects are manifested in the series of the coordinate bond lengths.
