Selective Construction of Pd₂Pt and PdPt₂ Triangles in a Sandwich Framework: Carbocyclic Ligands as Scaffolds for a Mixed‐Metal System

Abstract

Sandwich time! The mixed-metal triangular-trinuclear sandwich complexes of Pd(2)Pt and PdPt(2) were selectively synthesized. The Pd(2)Pt and PdPt(2) triangles in a cycloheptatrienyl sandwich framework were identified by (31)P NMR analyses of the tris-triphenylphosphine complexes (see scheme).
