The titanocene alkoxides with the alkoxy carbon atom tethered to one of the cyclopentadienyl ligands showing the crystallographic Ti-O-C angle close to 133 degrees are a suitable group of compounds to be compared with the [Cp*2TiOR] compounds, where the Ti-O-C angle is about 174 degrees for 3 and 7 and 180 degrees for 4.
