The present paper describes the synthesis and reactivity of platinum based trinuclear carbonyl clusters of the type L₂PtRu₂ (CO)₈ where L₂ = 1,3-bis(diphenylphosphino)propane (dppp) and 1,2-bis(diphenylphosphino)butane (dppe). Reaction of these trinuclear clusters with elemental sulfur yielded the unexpected formation of platinacyclosulfides. The products were isolated and identified as platinacyclodisulfide and platinacyclotetrasulfide by analytical and spectroscopic techniques.
