Simple new one-pot syntheses from metal salts, CO, dppm and NaBH₄ and the crystal structures of [M₃(μ₃-CO)(Cl)(μ-dppm)₃]Cl (M = Pd, Pt) are reported. The structure of the triangulo Pd₃-containing cation is very similar to that already reported with a CF₃COO^- anion, including the disorder at the CO and Cl ligands. There is no disorder in the Pt cation. The CO asymmetrically caps one side of the Pt₃ face and the Cl^- ligand on the other side is weakly associated with only one of the Pt atoms. Convenient, high-yield syntheses of additional Pt-dppm and Pt-dppm-CO complexes are also reported.
