The molecular structure of Me 3TiCp in the gas phase

Abstract

The thermal average molecular structure of Me 3TiCp ★ has been determined by gas phase electron diffraction (GED). The GED data are consistent with a molecular model in which the TiMe 3 fragment has C 3 v symmetry and the TiCp ★ fragment has C 5 v 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.
