The title molecule, [TiCl2(C5H5)(C18H21O)], has a pseudotetrahedral be
nt metallocene structure in which the cyclopentadienyl ring is symmetr
ically bonded to Ti [range of Ti-C distances 2.36(1)-2.41(1)Angstrom],
but the substituted cyclopentadienyl ring adopts asymmetrical bonding
[Ti-C 2.33(1)-2.48(1)Angstrom] due to the interaction of the large su
bstituent with the Cl(2) atom. The angle C(11)-C(1)-C(21) is 111.1(8)d
egrees with the large substituent occupying a cis position with respec
t to the substituted ring.
