The molecular structure of Me3TiCp* in the gas phase

The thermal average molecular structure of Me3TiCp★ has been determined by gas phase electron diffraction (GED). The GED data are consistent with a molecular model in which the TiMe3 fragment has C3v symmetry and the TiCp★ fragment has C5v symmetry. No static tilt of the methyl groups attached to titanium can be detected, although a flattening of the methyl groups with Ti-C-H 103.8(1.2)° is obtained. The Ti-C(Me) bond distance is 210.7(5) pm, and the Ti-C(Cp★) distance 238.0(5) pm.Norwegian Research Council for Science and HumanitiesVISTA progra
