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)(PPh3)2和cis-Pt(hp)2(PPh3)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。

cis-PtCl(hp)(PPh3)2.py.EtOH (I; Hhp = 2-hydroxypyridine) and cis-Pt(hp)2(PPh3)2.2H2O (II) were prepared Their crystal structures have been determine by x-ray diffraction. In the two complexes the Pt(II) ion has an irregular square-planar stereochem. and the hp ligands coordinate to the Pt(II) through N in the pyridonate form. Crystal data for I: triclinic, space group P1, Z = 2, R = 0.051, Rw = 0.053; II, monoclinic, space group P21/n, Z = 4, R = 0.049, Rw = 0.058.
