Dichloridobis{N-[(dimethylamino)dimethylsilyl]-2,6-dimethylanilido-²N,N'}hafnium(IV)

Abstract: In the monomeric hafnium(IV) title compound, [Hf(C₁₂H₂₁N₂Si)₂Cl₂], the Hf atom is N,N'-chelated by the N-silylated anilido ligand. The two ligands around the Hf atom are arranged cis to each other; a twofold rotation axis passes through the Hf atom. The two ends of the N-Si-N chelating unit exhibit different affinities to the metal center. The Zn-N_amino bond is longer than the Zn-N_anilido bond. Along with two Cl atoms, the six-coordinate Hf atom demonstrates a highly distorted octahedral geometry.
