Popis: Three new RuPt clusters [Ru6Pt(μ6 -C)(C6H5CH3)(CO)13(COD)] (2), [Ru6Pt(μ6 -C)(C6H5CH3)(CO)14(PPh3)] (3) and [Ru6Pt2(μ6 -C)(C6H5CH3)(CO)13(PPh3)3] (4) were obtained from the reaction of [Ru6(μ6 -C)(C6H5CH3)(CO)14] (1) with two different Pt precursors. Both 2 and 3 consists of a Ru6Pt cluster with face capped octahedron metal core, whereas, 4 has a unique Ru6Pt2 cluster core structure with doubly capped octahedron. Further, CO substitution behavior of 1 was studied with diphosphine ligands, which results in the formation of mono and bi substituted products, which also show the removal of the toluene cap by the dppe ligand. All the compounds were characterized structurally by X-ray diffraction analysis.
