含2-羟基吡啶负离子配体(hp^-)的铂(Ⅱ)配合物cis-PtCl(hp)(PPh_3)_2和cis-Pt(hp)_2(PPh_3)_2的结构

The Structures of Platinum Complexes Containing 2-Hydroxypyridinate Ligand (hp^-) cis-PtCl (hp) (PPh_3)_2 and cis-Pt(hp)_2 (PPh_3)_2

我们制得了两种含2-羟基吡啶负离子配体的铂(II)配合物:cis-PtCl(hp)(PPh_3)_2和cis-Pt(hp)_2(PPh_3)_2.其晶体结构测定的结果表明,两种配合物中的铂(II)离子呈近似平面的四边形配位.2-羟基吡啶负离子配体以酮式异构体形式通过氮原子配位于铂上.

The platinum complexes containing 2-hydroxypyridinate ligand(hp^-)cisPtGl(hp)(PPh_3)_2 and cis-Pt(hp)_2(PPh_3)_2 have been prepared. Their crystal structures have been determined by X-■ay diffra■tion. In the two complexes the Pt(Ⅱ) ion has an irregular square-planar stereochemistry and the hp^-ligands coordinate to the Pt(Ⅱ) through N in the pyridonate form.
