| Abstract: | The reaction of LnCl3·xTHF with Na(C5H4CH2CH2PPh2) followed by the in situ reaction with Na2(C14H10) afforded the (C5H4CH2CH2PPh2)Ln(C14H10)L complexes (Ln = Y or Lu and L = THF or DME). The structure of (C5H4CH2CH2PPh2)Lu(C14H10)(DME) was established by X-ray diffraction. In solution, there is an equilibrium between the complexes with the coordinated
and uncoordinated phosphorus atom.
Dedicated to Academician G. A. Abakumov on the occasion of his 70th birthday.
