Treatment of an open-cage fullerene, designated as MMK-9, with (Ph 3 P) 4 Pt in toluene solution at room temperature allows a (PPh 3 ) 2 Pt 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 PtC 2 P 2 coordination, rather than the usual η 2 -bonding to an intact C-C double bond of the fullerene. A remarkable open-cage fullerene with a four coordinate platinum atom incorporated into its rim has been prepared by cleavage of just one of the many carbon-carbon bonds of the fullerene.
