Abstract: 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)2CCH2SiMe3]2Y. 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.
