Synthesis and molecular structures of zirconium complexes that contain bidentate amido ligands

Abstract

Zirconium complexes that contain bidentate amido ligands, Zr 2{EtN(CH 2) 3NEt} 4 ( 1), Zr 2{PhN(CH 2) 2NPh} 4 ( 2), Zr{Me 3SiN(CH 2) 3NSiMe 3} 2 ( 3) and Zr{ trans- N, N′-diphenyl-1,2-diaminocyclohexane}Cl 2(THF) 2 ( 4), have been prepared by the reaction of lithium diamido reagents with ZrCl 4, and characterized by single crystal X-ray diffraction. The molecular structures of complexes 1– 4 are discussed.
