Reaction of [Yb(CpPh5)(C[triple bond]CPh)(thf)]2 (CpPh5 = pentaphenylcyclopentadienyl), prepared from Yb(C triple bond CPh)2 and HCpPh5 or Yb metal, HgPh(C[triple bond]CPh) and HCpPh5, with a controlled amount of diglyme (dig), and of Eu(C triple bond CPh)2, P triple bond CBut and dig, yield the unusual organolanthanoid(II) dicationic complexes [Yb(C[triple bond]CPh)(dig)(thf)2]2[CpPh5]2.4thf and [Eu(C
由Yb(C三键CPh)2与HCpPh5或Yb金属,HgPh(C三键] CPh制备的[Yb(CpPh5)(C [三键] CPh)(thf)] 2(CpPh =五苯基环戊二烯基)的反应)和HCpPh5,并具有受控的二甘醇二甲醚(dig)和Eu(C三键CPh)2,P三键CBut和dig,可产生不寻常的有机镧系元素(II)阳离子型复合物[Yb(C [三键] CPh )(dig)(thf)2] 2 [CpPh5] 2.4thf和[Eu(C三键CPh)(dig)2] 2 [P2C3But3] 2。
