Dark red crystals of the paramagnetic complex Cp*MoCl2(O) (Cp*=η5-C5(CH3)5) were obtained from the reaction of Cp*MoCl4 and water. The compound crystallizes in the triclinic space group P1̄ with a =8.654(2), b = 11.150(3), c=6.545(1) Å, α= 93.76(3), β = 91.12(3), γ= 85.68(3)°, V = 628.3(3) Å3, Dcalc=l.681 g/cm3 and Z=2. The structure was solved and refined based on 1463 reflections with Fo≥6σ(Fo) (6104 collected; Mo Kα radiation, λ=0.71073 ») and R=0.033. The piano-stool structure, exhibiting a distorted Cp* ligand, is compared with reported structures for the closely related compounds, CpMoCI2(O) (Cp=η5-C5H5), Cp*VCl2(O) and Cp*ReCl2(O).
