Description
Summary:The 1 : 2 reaction of [Ti(η5-C5H5)2Cl2] and AgF in CHCl3/H2O yielded the fluoro analog [Ti(η5-C5H5)2F2] (1) in almost quantitative yield (C5H5 is the cyclopentadienyl group). The coordination about the TiIV atom formed by two fluoro ligands and the centroids of the cyclopentadienyl rings is distorted tetrahedral. The compound crystallizes in the orthorhombic space group C2cm. The lattice constants are a=5.9055(4),b=10.3021(5),c=14.2619(9) Å, and α=β=γ=90°. The complex has been characterized by elemental analyses and spectroscopic (IR, H1 NMR) data. A structural comparison of the four members of the [Ti(η5-C5H5)2X2] family of complexes (X=F,Cl,Br,I) is attempted.
