A deprotonation reaction of Cp2Ti(SH)2 with NaH in THF yields {Na2[CpTi(μ-S)(S)]2·4THF}2, generated by unexpected elimination of CpH. This anionic dimer is unique in that it is the first organometallic titanium species containing terminal sulfido ligands. The latter are stabilized by interactions with THF-solvated sodium cations, thus imposing a syn TiS configuration.
