合成并表征了一种吡啶-2-硫醇根桥联的环化双核铂配合物[Pt-2（ppy）（2）（ppy）（2）]（Hppy = 2-苯基吡啶，Hpyt =吡啶-2-硫醇）及其氧化的铂配合物[Pt_2Cl_2（ppy）（2）（pyt）（2）]。该二价配合物在溶液和固体状态下均表现出强烈的红色发光。对应于短的（PtPt）-Pt-.距离（2.849（1）埃）的[Pt-2（ppy）（2）（pyt）（2）]，二价和三价配合物之间的可逆转换容易发生的出现和消失的发光。
A cyclometalated dinuclear platinum(II) complex bridged with pyridine-2-thiolate ions, [Pt-2(ppy)(2)(ppy)(2)] (Hppy = 2-phenylpyridine, Hpyt = pyridine-2-thiol) and its oxidized platinum(III) complex, [Pt2Cl2(ppy)(2)(pyt)(2)] have been synthesized and characterized. The divalent complex exhibits intense red luminescence both in solution and in the solid states. Corresponding to the short (PtPt)-Pt-... distance (2.849(1)Angstrom) for [Pt-2(ppy)(2)(pyt)(2)], the reversible conversion between the divalent and trivalent complexes occurs easily with appearance and disappearance of the luminescence.
