C10H8Yb(THF)3 with Cp2V, vanadium-containing intermediates could be isolated. One of them, CpVC10H8VCp, has been characterized by X-ray diffraction. The crystals are monoclinic, space group P21/n, with a 907.0(5), b 798.8(3), c 1080.8(5) pm, β 105.21(4)°; Z = 2. The structure was refined to R = 0.0288 for 1131 observed reflections (Fo > 4σ(Fo)).
萘yC 10 H 8 Yb(THF)3与Cp 2 Cr,Cp 2 Co,Cp 2 Ni和Cp 2 V在THF中反应,得到Cp 2 Yb。在C 10 H 8 Yb(THF)3与Cp 2 V反应的情况下,可以分离出含钒的中间体。其中之一CpVC 10 H 8 VCp已通过X射线衍射表征。该晶体是单斜晶系,空间群P 2 1 / Ñ,具有一907.0(5),b798.8(3),c 1080.8(5)pm,β105.21(4)°;Z =2。对于1131个观察到的反射(F o >4σ(F o)),结构被细化为R = 0.0288 。
