The photolysis of the allylplatinum(IV) complex [PtBr(C3H5)(4-MeC6H4)2(bipy)], 1, bipy = 2,2'-bipyridine, in air yielded [{PtBr(4-MeC6H4)2(bipy)}2(μ-O2)], 2, the first diplatinum(IV) complex containing a single bridging peroxide ligand. The PtO-OPt bond distance in 2 is 1.481(3) Å. Complex 2 is thought to be formed by homolysis of the allyl-platinum bond of 1, followed by reaction of the platinum(III) intermediate [PtBr(4-MeC6H4)2(bipy)] with oxygen.
