7-phen)] (4), respectively. The crystal structure of trans-[Pt2Br4(SMe2)2(μ-4,7-phen)].C6H6 reveals that 4,7-phen bridges between two platinum centers in a slightly distorted square planar arrangement of the platinum. In this structure, both bromides are trans, while the PtBr2(SMe2) moieties are syn to each other. NMR data of mono and binuclear complexes of platinum 1–4 show that the binuclear complexes
摘要 顺式和反式-[PtCl2(SMe2)2] 与 4,7-phen (4,7-phen = 4,7-phenanthroline) 以 1:1 或 2:1 的摩尔比反应得到在形成单核和双核复合物反式-[PtCl2(SMe2)(4,7-phen)] (1) 和反式-[Pt2Cl4(SMe2)2(μ-4,7-phen)] (2) 时,分别. 产品已通过元素分析、1H、13C1H}、HHCOSY、HSQC、HMBC和
DEPT-135核磁共振谱进行了全面表征。1 的晶体结构表明
铂具有略微扭曲的方形平面几何形状。两种
氯化物都是反式的,线性偏差为 177.66(3)°,而 N-Pt-S 角为 175.53(6)°。类似地,顺式和反式-[PtBr2(SMe2)2] 的混合物与 4,7-phen 以 1:1 或 2:1 的摩尔比反应得到单核或双核配合物反式-[PtBr2(SMe2)( 4,7-phen)]
