Platinum cluster compounds: X-ray structures of phosphido-bridged bi- and tri-nuclear complexes with strong metal–metal bonds derived from [Pt(PPh3)4]

Abstract
Binuclear [(Pt2(PPh3)2(PPh2)2] and trinuclear [Pt3(PPh3)2(PPh2)3Ph] cluster compounds of platinum have been prepared from [Pt(Ph3P)4] and characterised by X-ray crystal structure analyses of their benzene solvates.
