A pair of new Pt(II)/Pt(IV) 2,2′-bipyridine cyclometalated rollover complexes have been synthesized and characterized. [Pt(bpy-H)(CH3)(PMe3)] (1), where bpy-H = κ2N,C-2,2′-bipyridine, was obtained from the electron-rich precursor cis-[Pt(CH3)2(DMSO)2] with a one-pot, two step synthesis; its reactivity has been tested with CH3I, giving the corresponding Pt(IV) complex cis-[Pt(bpy-H)- (CH3)2(I)(PMe3)] (2), which was fully characterized. Crystals suitable for X-ray analysis were obtained and allowed the determination of the structure of isomer 2A which is the product of the trans addition of CH3I, usually thought of as the kinetic product.
