Abstract

Lithiation of the diamine CH2(CH2NHSiMePh2)2 using n-butyl lithium and subsequent reaction with zirconium tetrachloride yielded the bis(chelate)-amidozirconium complex Zr{CH2(CH2NSiMePh2)2}2. The spirocyclic molecule has a distorted tetrahedral coordination at the zirconium centre with overall C2 symmetry broken only by the relative orientation of four phenyl rings. The bulky diphenylmethylsilyl substituents at the amido-N functions as well as the ligand backbone sterically protect the metal centre and render it inert towards conproportionation with zirconium chloride.
