Titan(IV)-Verbindungen mit hochphenylierten π-Cyclopentadienylliganden. Die Struktur von (π-C5H5)(π-C5Ph5)TiCl2
摘要:
The reaction of (pi-C5H5)TiCl3 with KC5Ph5 (4-Ph) in THF gives (pi-C5H5)(pi-C5Ph5)TiCl2 (5-Ph). (pi-C5H5)(pi-C5Ph4H)TiCl2 (5-H) can be prepared analogously. An X-ray diffraction study on 5-Ph has been undertaken. The Ti-C bond lengths for the C5Ph5 group are considerably longer than those for the C5H5 group; the averages are 2.53 +/- 0.03 and 2.39 +/- 0.04 angstrom, respectively.
