Diplatinum(III) tetrakis(β-diketonato) complexes exemplifying the unsupported Pt–Pt bond

Abstract
Coupling of tervalent ClPt(acac)2 moieties to form diamagnetic, directly Pt–Pt bonded [Pt2Cl2(acac)4] occurs in the course of oxidative addition of Cl2 to [Pt(acac)2][acac = R(CO)CH(CO)R′ and R/R′= Me/Me, Me/CF3 or Ph/Ph].
