摘要
The reaction of Pt(COD)2 with Ru(CO)5 at 25 °C produced the hexanuclear metal complex [PtRu2(C-O)9]2 (1) in 31% yield, which consists of an open cluster containing two ruthenium atoms bonded to two platinum atoms followed by two additional ruthenium atoms. Compound 1 reacted with dppe by a symmetrical cleavage of the molecule to yield PtRu2(CO)8(dppe) (2). The reaction of 1 with PhC2Ph produced the higher cluster Pt3Ru6-(CO)14(µ3-PhC2Ph)3 (3) in 30% yield. Compound 3 consists of a Pt3Ru3 octahedron with three ruthenium atoms capping triangular faces. It also contains three triply bridging PhC2Ph ligands. © 1990, American Chemical Society. All rights reserved.
