The unexpected anionic Zr (II) complex [Cp2Zr(CdropCPh) (eta(2):1, 2-PhC(2)CdropCPh)](-) was isolated from LiCdropCPh and Cp2ZrCl2 in THF, giving clear, evidce for a C-C coupling between two alkynyl moieties, one of them being eta(2)-bonded to the zirconium atom. The complex was characterized by elemental analysis, NMR, IR spectroscopy and X-ray diffraction. The synthesis reaction mechanism was discussed.
