Abstract

Three new platinum-ruthenium complexes: Pt3Ru 3(PBut 3)3(CO)12, 8, Pt5Ru3(PBut 3)3(CO) 12, 9 and PtRu3(PBut 3) 2(CO)83-PBut)(μ-H) 2, 10 were obtained from the reaction of Ru3(CO) 12 with Pt(PBut 3)2. Compound 8 was obtained from this reaction when conducted at 25 °C. Compounds 9 and 10 were obtained when the reaction was conducted at 68 °C. The structure of 8 consists of a central triangular cluster of three ruthenium atoms with one Pt(PBut 3) group bridging each of the three Ru-Ru bonds. The structure of 9 consists of a capped pentagonal bipyramidal cluster of eight metal atoms that is formed formally by the addition of two platinum atoms to 8. The structure of 10 contains a triangular cluster of three ruthenium atoms with a Pt(PBut 3) group bridging one of the Ru-Ru bonds. A t-butyl phosphido ligand formed by degradation of a molecule of PBut 3 bridges the three ruthenium atoms.
