Although η2-H−EXn σ-complexes are well-known when E is a Group 13 or 14 element (E=B, Al, Ga, C, Si, Ge, Sn), η2-H−EXn σ-complexes where E is a period 6 main-group element were previously unknown. Now the synthesis and structural characterization is presented of ruthenium σ-complexes [CpRu(PP)(η2-(H-Tl))]+ (PP=dppm, dppe), which contain TlH, a hydride of a period-6 main group element.
Abstract
Treatment of CpRuH(PP) (PP=dppm, dppe) with TlPF6 produced [CpRu(H)(Tl)(PP)]PF6. X-ray diffraction and computational studies suggest that the complexes contain a Ru−H−Tl 3c–2e bond and can be viewed as the first σ-complexes of period 6 main-group hydrides [CpRu{η2-(H−Tl)}(PP)]PF6 or [Tl{η2-H−RuCp(PP)}]PF6. The complexes can be stored as a solid at room temperature for days without appreciable decomposition, but are unstable in solution and evolved to the trimetallic complexes [{CpRu(PP)}2(μ-Tl)]PF6.

- 38The assignments of the ν(Ru–H) bands were confirmed by the absence of the IR bands in the IR spectra of [CpRu{η2-(D-Tl)}(PP)]PF6. DFT calculations predict that ν(Ru–D) and ν(Tl–D) of [CpRu{η2-(D−Tl)}(dppm)]PF6 should appear at 1348 and 562 cm−1, respectively, and that ν(Ru–D) and ν(Tl–D) of [CpRu{η2-(D−Tl)}(dppe)]PF6 should appear at 1334 and 601 cm−1, respectively. Unfortunately, these bands could not be confidently identified, because these regions are filled with the IR bands arising from other ligands.
