作为cis-[Pt（piam）2（NH3）2]·2 H2O（1，piam = pivalamidate）的类似物，合成了cis-[Pt（piam）2（NH 2C 3 H7）2]·H2O（2）和cis-[Pt（piam）2（NH 2C 4 H9）2]（3）两种铂单核配合物，并通过单晶X射线衍射对其结构进行了表征。正方形平面配合物2和3分别含有丙基和丁基基团，增强了疏水性。这两种化合物在plam配体中具有非配位的氧原子，其可以结合到第二金属，例如Cu 2+离子，以提供三核Pt-Cu-Pt络合物。2和3与Cu ~（2+）反应的UV-Vis和电子顺磁共振谱表明，两个化合物都形成了双核Pt-Cu配合物中间体。
As analogs ofcis-[Pt(piam)2(NH3)2]·2H2O (1, piam = pivalamidate), two kinds of platinum mononuclear complexes,cis-[Pt(piam)2(NH2C3H7)2]·H2O (2) andcis-[Pt(piam)2(NH2C4H9)2] (3), have been synthesized and characterized by single-crystal X-ray analyses. The square-planar complexes2and3contain propyl and butyl moieties, respectively, enhancing the hydrophobicity. Both compounds have non-coordinated oxygen atoms in the piam ligands that can bind to a second metal, such as the Cu2+ion, to afford trinuclear Pt–Cu–Pt complexes. UV–Vis and electron paramagnetic resonance spectra of the reaction of2and3with the Cu2+ion show that both compounds form dinuclear Pt–Cu complexes as intermediates.
