A general route for the synthesis of tetranuclear clusters containing closed triruthenium and triosmium triangles
Abstract
The cluster compounds [N(PPh3)2][M3M′(CO)13](M = Ru or Os, M′= Co) and [N(PPh3)2][M3M′H(CO)13](M = Ru or Os; M′= Fe, Ru, or Os) have been prepared in good yield by the reaction of an appropriate tetracarbonylmetalate with the bis(acetonitrile) complexes, [M3(CO)10(NCMe)2](M = Ru or Os). The anionic clusters have been protonated, where possible, to give the corresponding neutral hydride clusters. In addition to known tetranuclear clusters synthesised by this method, we report the new cluster compounds [N(PPh3)2][Os3RuH(CO)13], [N(PPh3)2][Ru3OsH(CO)13], and [Ru3OsH2(CO)13].
