Abstract

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, D_calc=l.681 g/cm³ and Z=2. The structure was solved and refined based on 1463 reflections with F_o≥6σ(F_o) (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).
