  摘要：

  Reactivity studies of three different tris(2-pyridyl)-stannate derivatives toward the Ln(II) compounds [Ln-(Cp*)(2)(OEt2)] (Ln = Yb, Sm; Cp* = eta(5)-C5Me3) are described. Thus, treatment of [La(Cp)(3){Sn(2-py(5Me))(3)Li(thf)}] (Cp = eta(5)- C5H5, py(5Me) = C5H3N-5-Me) with [Yb(Cp*)(2)(OEt2)] afforded the pentametallic complex [Yb{Sn(2-py(5Me))(3)La(Cp)(3)}(2)] (1) with the Yb2+ cation encapsulated by two tris(2-pyridyl)stannate units and two unsupported Sn-La bonds in terminal positions. On the other hand, reaction of the bis(stannate) complex [Yb{Sn(2-py(3Me))(3)}(2)] (py(3Me) = C5H3N-3-Me) with [Yb(Cp*)(2)(OEt2)] gave the heteroleptic complex [Yb(Cp*){Sn(2-py(3Me))(3)}] (2). Moreover, two samarium(III) compounds [Sm(Cp*)(2){MEt2(2-py(5Me))(2)}] with M = Ga (3), In (4) were obtained in a reductive approach. Compounds 1-4 have all been characterized by NMR spectroscopic and X-ray crystallographic studies.
