Preparation of mixed-metal polynuclear complexes by stepwise phosphine-bridging reaction
The phosphine-bridged Pd(II)-Pt(II)-Pd(II) trinuclear and Rh(III)-Pd(II)-Pt(II)-Pd(II)-Rh(III) pentanuclear complexes with tris[2-(diphenylphosphino)ethyl]phosphine (PP3) ligands were successfully prepared by stepwise phosphine-bridging reaction of the terminal phosphino groups of the PP3 ligands on the Pd(II) cores.
