| Abstract: | The chelating diamide lithium complex [Me2Si{NLiCH(Me)Ph}2]2 (1) was synthesized. The X‐ray structure of complex 1 reveals that in the solid state it is a dimer; every lithium atom is three coordinated. The [{Me2Si{NCH(CH3)Ph}2}ZrCl2LiCl(OEt2)2]2 (2) and [{Me2Si{NCH(CH3)Ph}2}HfCl2LiCl(OEt2)2]2 (3) complexes were formed by treatment of complex 1 with ZrCl4 and HfCl4 respectively in diethyl ether at ambient temperature. Complexes (2) and (3) were also characterized by X‐ray single‐crystal diffraction. Copyright © 2005 John Wiley & Sons, Ltd. |
