A doubly bridged isodicyclopentadienyl zirconium complex: bis{N‐(3,5‐dimethylphenyl)‐N‐[(η5‐isodicyclopentadien‐2‐yl)dimethylsilyl]amido‐κN}zirconium(II) diethyl ether solvate

Abstract:Transmetallation of the dilithium salt of (3,5‐dimethyphenyl­amino)(isodicyclopentadienyl)dimethylsilane by treatment with zirconium tetrachloride in a 2:1 ratio leads to the substitution of all four chloride ligands. With the applied stoichiometry, the title complex, [Zr(C20H25NSi)2]·C4H10O, was obtained and crystallized from diethyl ether. X‐ray diffraction characterization showed that both isodi­cyclo­penta­dienyl ligands (alternatively called 4,5,6,7‐tetrahydro‐4,7‐methano‐1H‐indene) are complexed to the metal on their exo face in a completely stereoselective manner and that they are η5‐bonded to the Zr atom.
