A series of palladium(II) complexes with 1,2-bis[di(benzo-15-crown-5)phosphino]ethane ligand (dbcpe), [Pd(dbcpe)X2] (X = Cl 1, Br 2 and I 3), have been successfully synthesised and characterised. The X-ray crystal structure of dbcpe has also been determined. The cation-binding properties of the complexes have been studied and the stability constants with alkali metal cations determined. The crown-free analogue of dbcpe, 1,2-bis[bis(3,4-dimethoxyphenyl)phosphino]ethane (ddmppe), and the related complexes have also been prepared and comparison studies have been made.
一系列含有1,2-双[二(苯并-15-冠-5)膦基]乙烷配体（dbcpe）的钯（II）配合物，即[Pd(dbcpe)X₂]（X = Cl 1、Br 2和I 3），已成功合成并表征。还测定了dbcpe的X射线晶体结构。研究了这些配合物的阳离子结合性能，并测定了与碱金属阳离子的稳定常数。还制备了dbcpe的无冠类似物1,2-双[双(3,4-二甲氧基苯基)膦基]乙烷（ddmppe）及其相关配合物，并进行了比较研究。
