  Na+ and Ca2+ ion selective pyridylcarboxylate rings of Pd(II) and Pt(II)

  摘要：

  一系列具有中心矩形腔的双核Pd(II)和Pt(II)配合物通过使用吡啶羧酸酯作为间隔基和磷配体[1,1'-双(二苯基膦基)二茂铁(dppf)和三苯基膦]作为支持配体自组装而成。其中一些配合物通过捕获外来的碱金属或碱土金属离子而表现出金属冠结构。两种Pt(II)环状结构选择性地与Na+结合，而Pd(II)环状结构则偏好与Ca2+结合。这种环内金属离子的络合作用因汇聚的羰基侧链而得以促进，并受到配位的三氟酸盐的支持。亲和性和选择性通过侧链羰基和环的空间构型控制实现，这些构型依赖于间隔基的异构性。这些金属间配合物通过X射线单晶衍射和溶液光谱学(NMR和ESI-MS)进行了表征，揭示了Na+和Ca2+的不同局部几何结构。

  An array of Pd-II and Pt-II supramolecular assemblies have been constructed using pyridyl carboxylates as spacers and phosphines [(C5H4PPh2)(2)Fe (dppf) and PPh3)] as supporting ligands. Different molecular topologies such as squares, triangles, rectangles, and polymers can be controlled by the spatial and directional character of the spacer. A change of the denticity of the phosphine does not affect the topological outcome. Significant differences, however, are observed for the congeneric analogues, with Pd-II showing a more pronounced tendency toward coordination polymer formation and its attached carboxyl a higher affinity toward Ag+. The ability of these assemblies to capture cations, such as Na+ in [Pt3Na(3-NC5H4CO2)(3)(OTf)(3)(PPh3)(6)](+) through hydrogen bonding or Ag+ in [PdAg(2-NC5H4CO2)(OTf)(2)(dppf)] through dative bonding, is described and compared. All of the complexes are structurally characterized by single-crystal X-ray crystallography.
