Abstract
A series of trifluoro metal complexes of titanium, zirconium and hafnium containing the n-propyltetramethylcyclopentadienyl ligand (C(5)Me(4)nPr) have been synthesised by metathesis reactions of the trichloro analogue using three equivalents of Me3SnF. X-ray analysis of (C(5)Me(4)nPr)TiF3 1 confirms the presence of two (C(5)Me(4)nPr)TiF3 moieties with two fluorine atoms bridging the metal atoms resulting in a centre of symmetry. The starting materials (C(5)Me(4)nPr)MCl3 (M=Zr, Hf) were prepared by reaction of (C(5)Me(4)nPr)Li with MCl4 (M=Zr, Hf).
