The reaction of LuCl₃(THF)₃ with Na(1,3-Ph₂C₅H₃) followed by the in situ reaction with Na₂[Ph₄C₂] produced (1,3-Ph₂C₅H₃)Lu(Ph₄C₂)(THF) (1). The structure of 1 was established by X-ray diffraction. In the crystal structure of 1, the bis-allyl η⁶-coordination of the tetraphenylethylene dianion to the lutetium cation was observed. The structures of (1,3-Ph₂C₅H₃)LuCl₂(THF)₃ and (C₅H₅)LuCl₂(THF)₃ were determined by X-ray diffraction.
