Dioxo(η⁵-pentamethylcyclopentadienyl)(trimethylsilylmethyl)tungsten(VI)

(η⁵-C₅Me₅)WO₂(CH₂SiMe₃), which has crystallographic mirror symmetry, exhibits the three-legged piano stool geometry typical for complexes of this type. The pentamethylcyclopentadienyl ligand is asymmetrically bound to the metal atom [W-C = 2.321 (8)–2.477 (4) Å]. The W=O and W—C(alkyl) distances are 1.717 (4) and 2.128 (8) Å, respectively.
