Two new platinum(II) complexes, namely [PtCl(sac)(COD)] (1) and [Pt(sac)(COD)] (2) (sac = saccharinate and COD = 1,5-cyclooctadiene), were synthesized and characterized by elemental analysis, IR, NMR, ESI-MS spectroscopic and thermal analysis (TG/DTA) methods. The platinum(II) complexes were prepared from the reaction of [PtCl(COD)] with Na(sac)•2HO. The addition of the sac ligand resulted in the replacement of 1 and 2 chlorido ligands in [PtCl(COD)] to yield 1 and 2, respectively. The structures of the complexes were determined by single crystal X-ray diffraction and showed a distorted square planar coordination geometry around platinum(II). COD acted as a π-donor ligand, while sac was N -coordinated in both complexes. The TG/DTA data indicated that both complexes were thermally stable up to 220 °C in air and their thermal decompositions yielded Pt as a final product. Complexes 1 and 2 were also designed as possible precursors to synthesize new mixed-ligand platinum(II) sac complexes in a one-pot reaction.
合成了两种新型铂（II）配合物，即[PtCl(sac)(COD)]（1）和[Pt(sac)(COD)]（2）（sac = 糖精，COD = 1,5-环辛二烯），并通过元素分析、红外光谱、核磁共振、电喷雾电离质谱和热分析（TG/DTA）方法对其进行了表征。铂（II）配合物由[PtCl(COD)]与Na(sac)•2H₂O反应制备而成。糖精配体的加入导致[PtCl(COD)]中的1个和2个氯配体被取代，分别生成配合物1和2。通过单晶X射线衍射确定了配合物的结构，结果表明铂（II）周围呈现扭曲的平面正方形配位几何结构。COD作为π供体配体，而在两种配合物中糖精均通过N原子配位。TG/DTA数据表明，两种配合物在空气中加热至220°C时均具有热稳定性，其热分解的最终产物为Pt。配合物1和2还被设计为在一锅反应中合成新型混合配体铂（II）糖精配合物的潜在前体。
