摘　　要：Reaction of（C5Me4SiMe3）Y（CH2SiMe）2（THF） with two equivalents of iPrN=C=NiPr in hexane at room temperature afforded a mixed-ligand yttrium complex（C5Me4SiMe3）（iPrN）2CCH2SiMe32Y.X-ray diffraction revealed that the center metal was nine-coordinated by one cyclopentadienyl ring and two amidinate ligands, and adopted a four-legged piano stool geometry.Reaction of（C5Me4SiMe3）Y（CH2SiMe）2（THF） with two equivalents of iPrN=C=NiPr in hexane at room temperature afforded a mixed-ligand yttrium complex（C5Me4SiMe3）（iPrN）2CCH2SiMe32Y.X-ray diffraction revealed that the center metal was nine-coordinated by one cyclopentadienyl ring and two amidinate ligands, and adopted a four-legged piano stool geometry.
