The single crystal X-ray diffraction study of [(η5-C5H4SiMe3)2LuCl]2, prepared from LuCl3 and Na[C5H4SiMe3], shows the compound to be a centrosymmetric dimer with two η5-bonded cyclopentadienyl rings and two symmetrically bridging chlorine atoms coordinated to each of the two metal centers. The coordination geometry around the lutetium atoms is that of a distorted pseudo tetrahedron. The Lu-C(Cp) distances lie within the narrow range of 2.571 - 2.608 Å . The Lu-Cl bond lengths are 2.639(1) and 2.653(1) Å . The crystal structure shows no significant intermolecular contacts.
