Abstract

Reaction of [WCl₄(O)] with excess of the diGrignard reagent o-C₆H₄(CH₂MgC1)₂ in tetrahydrofuran (thf) yields [W(CH₂C₆H₄CH₂-o) ₃] (1), a thermally robust, reversible one-electron-reducible complex, of quasi 3/m symmetry with the o-xylidene ligand planes aligned parallel to the molecular axis and unusually folded, with significant, and possibly stabilising, W-π interactions, as shown by its X-ray structure determination, the mean W-C_αH₂ and W-C _β distances being 2.21 and 2.48 Å respectively.
