Crystal structure of the formal 20 electron zirconocene penta-fulvene complex Cp₂Zr(η⁵,η¹-adamantyl-idene-penta-fulvene):toluene:n-hexane = 1:0.125:0.125.

ABSTRACT: The crystal structure of a solvated zirconocene penta-fulvene complex with a bulky adamantyl-idene substitution pattern, namely (η⁵,η¹-adamantyl-idene-penta-fulvene)bis-(η⁵-cyclo-penta-dien-yl)zirconium(IV)-toluene-n-hexane (8/1/1), [Zr(C₁₅H₁₈)(C₅H₅)₂]·0.125C₇H₈·0.125C₆H₁₄, is reported. Reducing zirconocene dichloride with magnesium results in the formation of a low-valent zirconocene reagent that reacts readily with adamantyl-idene-penta-fulvene to give the aforementioned complex. Single crystal X-ray diffraction proves the dianion-like η⁵:η¹ binding mode of the fulvene ligand to the central Zr^IV atom. The asymmetric un
