reactions were observed for [Pt2(CH3)4(μ-S(CH3)2)2] with the ligands (S)-C4H3SCHNCHCH3C6H5 and C4H3SCHNC6H5, and the corresponding monocyclometalated species. A mechanism of formation is proposed with the support of DFT calculations. The complexes show emission, in solution, at room temperature, with emission bands red-shifted ∼200 nm, excited state lifetimes of the order of 1 μs, and modest quantum yields
