The bis(pentamethylcyclopentadienyl)thorium(IV) complex Cp2*ThI2 (Cp* = η5-C5Me5) was readily synthesized from the dibromo derivative Cp2*ThBr2 using a slight excess of trimethylsilyl iodide (Me3SiI). The thorium complex Cp2*ThI2 exhibits a ‘bent metallocene’ structure, as determined by single-crystal X-ray diffraction (monoclinic, space group P21/n; a = 8.572(2), b = 16.718(3), c = 15.881(2) Å; β = 98.16(2)o; V = 2252.8(8) Å3; Z = 4).
