  Synthesis and structures of Group 4 trimethylhydrazido complexes

  摘要：

  Chlorotris(trimethylhydrazido)titanium, TiCl(NMeNMe2)(3), was synthesized by reacting TiCl2(NMeNMe2)(2) with 1 equiv. of LiNMeNMe2. Tetrakis(trimethylhydrazido)zirconium and hafnium, M(NMeNMe2)(4), were prepared from MCl4 and 4 equiv. of LiNMeNMe2 but Ti(NMeNMe2)(4) could not be prepared cleanly from TiCl4. Instead, it was synthesized from TiCl(NMeNMe2)(3) and LiNMeNMe2. X-ray crystallographic studies show that TiCl(NMeNMe2)(3) and Ti(NMeNMe2)(4) have three bidendate hydrazide ligands and Zr(NMeNMe2)(4) has four bidendate ligands. (C) 2002 Elsevier Science B.V.
