An Anionic Dimer of Cyclopentadienyl- Titanium (IV) Sulfide: A Potential Precursor for Heterometallic Assemblies

Abstract

Reaction of Cp 2 Ti(SH) 2 with lithium salts in THF yields the cluster Li 6 [CpTi(μ-S) 3 ] 2 •6THF, generated by elimination of CpH. This anionic dimer is unique that during the preparation none of the sulfur atoms of the precursor has been eliminated and the Ti-S-H groups are completely converted to Ti-S-Li bonds. The crystal structure indicates the presence of all Ti-S single bonds in bridging positions of the titanium cluster.
