Penta­carbonyl-2κ(5) C-chlorido-1κCl-bis­[1(η(5))-cyclo­penta­dien­yl][μ-oxido(phenyl)methylene-1:2κ(2) O:C]hafnium(IV)tungsten(0)

The title compound, [HfW(C(5)H(5))(2)(C(7)H(5)O)Cl(CO)(5)] or [W(CO)(5)(C(7)H(5)O){Hf(C(5)H(5))(2)Cl}], contains two metal centres, with a (tungstenpenta­carbon­yl)oxy­phenyl­carbene unit coordinated to a hafnocene chloride. The Hf—O—C angle is nearly linear, and the C=O distance is slightly shorter than for equivalent alkoxy­carbenes. One of the cyclo­penta­dienyl (Cp) rings undergoes an offset face-to-face π–π inter­action [3.495 (7) Å] with the symmetry-related Cp ring of a neighbouring mol­ecule.
