Reaction of [Pt(dppy)2Cl2] with NaSH in the presence of triethylamine in MeCN produces a luminescent dimeric [Pt2(µ-S)2(dppy)4] complex 1 which is characterized by X-ray crystallography; its unusual reactivity with CH2Cl2 to give novel monomeric [Pt(dppy)2(S2CH2)]2, identified by both NMR spectroscopy and X-ray crystallography, is described (dppy = 2-diphenylphosphinopyridine).
在MeCN中,[Pt(dppy)2Cl2]与NaSH在三乙胺存在下反应,生成发光的二聚体[Pt2(µ-S)2(dppy)4]络合物1,其性质已通过X射线晶体学测定;它与CH2Cl2反应生成新颖的单体[Pt(dppy)2(S2CH2)]2,其性质已通过核磁共振光谱学和X射线晶体学测定,并进行了描述(dppy = 2-二苯基膦吡啶)。
