Palladium(II) complexes with benzodithia-12(18)-crown-4(6) ethers were demonstrated to have a cis-configured S2PdY2 fragment (Y = Cl, OAc). In the case of Pd(II) and benzodithia-21-crown-7 ethers, only complexes with a trans configuration of the S2PdY2 fragment form. In the case of Pd(II) and nitrobenzomonothia-15-crown-5 ether, only 2(ligand):1(Pd) complex with trans configuration of the core fragment
合成了一系列与硝基和甲酰基苯并硫杂的皇冠醚衍生物的钯(II)配合物。通过NMR,X射线衍射分析和量子化学计算(密度泛函理论)研究了配合物的空间结构。发现孔的大小和配体的密度是决定硫代皇冠-醚配合物的几何构型的关键因素。钯(II)配合物与benzodithia-12(18)-crown-4(6)醚被证明具有顺式构型的S 2 PdY 2片段(Y = Cl,OAc)。对于Pd(II)和benzodithia-21-crown-7醚,仅具有S 2 PdY 2反式构型的配合物片段形式。在Pd(II)和硝基苯并甲硫醚-15-冠-5醚的情况下,仅形成具有反式构型的核心片段的2(配体):1(Pd)配合物。
