Tungsten-platinum μ-carbido and μ-methylidyne complexes.

Reactions of the lithiocarbyne [W][triple bond, length as m-dash]CLi ([W] = W(CO)2(Tp*); Tp* = tris(dimethylpyrazolyl)borate) with divalent platinum complexes [PtCl(terpy)]PF6, [PtCl2(η-C4R4)] (R = Me, Et), and [PtCl2(phen)] afford access to μ-carbido, μ-methylidyne and carbyne-based metallo-ligand complexes [Pt(C[triple bond, length as m-dash][W])(terpy)]PF6, [Pt(μ-HC[triple bond, length as m-dash][W])2] and [Pt(C[triple bond, length as m-dash][W])Cl(phen-C[triple bond, length as m-dash][W]-2)], respectively, the last of which provides a rare example of intermolecular organometallic nucleophilic attack at coordinated phenanthroline.
