Abstract

Treatment of an open-cage fullerene, designated as MMK-9, with (Ph₃P)₄Pt in toluene solution at room temperature allows a (PPh₃)₂Pt unit to be incorporated into the rim of the cage so that it becomes an integral part of the carbon cage skeleton. The structure of the adduct has been determined by single crystal X-ray diffraction and reveals that the platinum atom has planar PtC₂P₂ coordination, rather than the usual η²-bonding to an intact C-C double bond of the fullerene.
