Isolation of a Stable Precursor for [Pt0(P−P)] and Its Reductive Addition to Ru3(CO)9(μ3-S)2 Giving Square Heterometallic Clusters Supported by Two Face-Capping μ4-Sulfides [P−P = (C5H4PPh2)2M; M = Fe, Ru]

Two labile but air-stable Pt(0) complexes Pt(η2-P−P)(η2-dba) [dba = dibenzylideneacetone; P−P = 1,1‘-bis(diphenylphosphino)ferrocene (dppf) (3a) or 1,1‘-bis(diphenylphosphino)ruthenocene (dppr) (3b...
