The (Phenylethynyl)cuprate europium complex {[(PhC⋮C)3Cu][Eu(Py)(THF)2]}2 (1) was synthesized by reaction of Eu with PhC⋮CCu in pyridine. The cuprate ytterbium complex {[(PhC⋮C)3Cu][Yb(THF)2]}2 (2) was synthesized by reaction of Yb with PhC⋮CCu in THF in the presence of a catalytic amount of ytterbium diiodide and also by the reaction of (PhC⋮C)2Yb with PhC⋮CCu.
