چکیده
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 (tungstenpenta-carbon-yl)oxy-phenyl-carbene 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 alkoxy-carbenes. One of the cyclo-penta-dienyl (Cp) rings undergoes an offset face-to-face π-π inter-action [3.495 (7) Å] with the symmetry-related Cp ring of a neighbouring mol-ecule.
