Heterobimetallic μ₂-carbido complexes of platinum and tungsten

The tungsten-platinum μ-carbido complex [WPt(μ-C)Br(CO)2(PPh3)2(Tp∗)] (Tp∗ = hydrotris(dimethylpyrazol-1-yl)borate) undergoes facile substitution of both bromide and phosphine ligands to afford a diverse library of μ-carbido complexes that includes [WPt(μ-C)Br(CO)2(dppe)(Tp∗)], [WPt(μ-C)(NCMe)(CO)2(PPh3)2(Tp∗)]OTf, [WPt(μ-C)(S2CNEt2)(CO)2(PPh3)(Tp∗)], [WPt(μ-C)(bipy)(CO)2(PPh3)(Tp∗)]PF6, [WPt(μ-C)(phen)(CO)2(PPh3)(Tp∗)]PF6, [WPt(μ-C)(terpy)(CO)2(Tp∗)]PF6, [WPt(μ-C)(CO)2(PPh3)(Bp∗)(Tp∗)], [WPt(μ-C)(CO)2(PPh3)(Tp∗)2] and [WPt(μ-C)(bipy)(CO)2(PPh3)(Bm)(Tp∗)], most of which have been structurally charcaterised.
