Crystal and molecular structure of [(eta(5)-C5H4SiMe3)(2)LuCl](2): A precursor for the production of Lu2O3 films

摘要

The single crystal X-ray diffraction study of [(eta(5)-C5H4SiMe3)(2)LuCl](2), prepared from LuCl3 and Na[C5H4SiMe3], shows the compound to be a centrosymmetric dimer with two eta(5)-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 Angstrom. The Lu-Cl bond lengths are 2.639(1) and 2.653(1) Angstrom. The crystal structure shows no significant intermolecular contacts.
