  摘要：

  理解和控制自组装结构的拓扑在超分子化学中起着基本作用。在这里，我们描述了通过四个不同的刚性和柔性配体的无模板自组装来制备一系列具有Cp * Rh构建基块的四核金属矩形和六核三叶结。三叶结与相应的大环之间的转化可以利用集中效应来诱导。值得注意的是，六核三叶结5进一步组装，通过酰胺氧原子与次要金属离子Na + / K +的配位提供了[12 + 1]异核双三叶结（5a / 5b / 5c / 5d）的罕见例子。 / Ca2 + / Cd2 +。合成结果得到单晶X射线衍射分析的支持。

  Four polymeric d(10) metal terephthalate complexes incorporating bis-pyridinecarboxamide building blocks were prepared to explore the effect of the central metal ion or the fluorine substituent of the ligand on the topology and entanglement of coordination networks. The combination of Zn-II terephthalate with a fluorinated ligand leads to a noninterpenetrated coordination layer with honeycomb (hcb) topology for complex 1. Interestingly, the other three materials display the unusual entangling coordination networks. For 2, the reaction of zinc terephthalate with nonfluorinated ligand affords three-dimensional diamond (dia) architecture of [3 + 3] interpenetration, while the Cd-II terephthalate complexes 3 and 4 with the two types of bis-pyridinecarboxamide tectons show the isostructural self-penetrating framework with unique 8-connected (4(17).6(11)) topology.
• Syntheses and studies of flexible amide ligands: a toolkit for studying metallo-supramolecular assemblies for anion binding

  The syntheses of seven flexible bidentate bis-pyridyl diamide and four monodentate pyridyl amide ligands containing central amide units are described. The bis-pyridyl ligands were prepared in one step from commercially available compounds in moderate to good yield. These compounds all possess external metal coordinating pyridyl groups and internal amide functionalities, with the potential to bind anions. Crystal structures of six of the bis-pyridyl diamide ligands are described. The four compounds with xylene cores N,N'-[1,3-phenylenebis(methylene)]bis-3-pyridinecarboxamide 1, N,N'-[1,3-phenylenebis(methylene)]bis-4-pyridinecarboxamide 2, N,N'-[1,4-phenylenebis(methylene)]bis-3-pyridinecarboxamide 3 and N,N'-[1,4-phenylenebis(methylene)]bis-4-pyridinecarboxamide 4 crystallize with extensive amide N-H center dot center dot center dot O=C hydrogen bonding between the diamide compounds, giving rise to two and three dimensional hydrogen bonded networks. N,N'-Bis(3-pyridylmethyl)benzene-1,3-dicarboxamide 5, the only compound with the amide groups directly attached to a central benzene core, was not able to be crystallised. N,N'-2,6-Bis(3-pyridylmethyl)pyridine dicarboxamide 6 and N,N'-2,6-bis(4-pyridylmethyl)pyridine dicarboxamide 7 have a mismatch of hydrogen bond donor and acceptor regions preventing ready involvement of the amide NH groups in network formation. For comparison we also prepared compounds N,N'-2'-propyl-6-(3-pyridylmethyl)pyrid me dicarboxamide 10 and N,N'-2'-propyl-6-(4-pyridylmethyl)pyridine dicarboxamide 11 with two amide groups but only the one external donor pyridyl moiety, and compounds N-6-[(3-pyridylmethyl amino)carbonyl]-2-pyridinecarboxylic acid methyl ester 8 and N-6-[(4-pyridylmethylamino)-carbonyl] -2-pyridinecarboxylic acid methyl ester 9, which have only the one amide.
