Dinuclear alkynyllanthanoid(II) dications with pentaphenylcyclopentadienyl or tri-tert-butyldiphosphacyclopentadienyl counter ions.
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 triple bond CPh)(dig)2]2[P2C3But3]2 respectively.
