四个新的Co Ⅱ和Ni Ⅱ配位聚合物：{[Co（mip）（bpa）]}n（1），{[Co（mip）（bpp）]}n（2），{[Ni（mip）（bpa）]}n（3），{[Ni（mip）（bpp）（H2O）]}n（4）（H2 mip = 5-甲基间苯二甲酸，bpa = 1，2-二（4-吡啶基）-乙烷，bpp = 1，3-二（4-吡啶基）-丙烷）的合成。通过单晶X射线衍射分析确定了它们的晶体结构，并通过元素分析和红外光谱对其进行了表征。配合物1和3的结构相似，除了不同的中心金属离子外，都是一个跨越两个不同方向的无限双层。化合物2由于bpp配体的GG构象而呈现一维聚合物带状结构，并通过C-H π相互作用进一步延伸为二维超分子层。配合物4具有由超分子相互作用形成的双层互穿（3，5）-连接hms网络。四种配合物的结构和拓扑结构的差异表明，中心金属离子和N-给体辅助配体的特性在构建新型配位聚合物中起着重要作用。在2000 G、2-300 K温度范围内研究了化合物1-4的磁性.
Four new CoII and NiII coordination polymers, {[Co(mip)(bpa)]}n (1), {[Co(mip)(bpp)]}n (2), {[Ni(mip)(bpa)]}n (3), {[Ni(mip)(bpp)(H2O)]}n (4) (H2mip = 5-methylisophthalic acid, bpa = 1,2-bi(4-pyridyl)-ethane, bpp = 1,3-di(4-pyridyl)-propane), were prepared viahydrothermal reactions based on H2mip and two bridging dipyridyl ligands. Their crystal structures were determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses and IR spectra. Complexes 1 and 3 are structurally similar with an infinite bilayer spanning two different directions except for the different central metal ions. The structure of 2 shows a 1D polymeric ribbon due to the GG conformation of the bpp ligand, which is further extended to a 2D supramolecular layer by the C–H⋯π interactions. Complex 4 possesses a two-fold interpenetrating (3,5)-connected hms network constructed from supramolecular interactions. The structural and topological differences of the four complexes demonstrate that the central metal ions and the characteristics of the N-donor auxiliary ligands play significant roles in constructing the novel architectures of coordination polymers. The magnetic properties of 1–4 were studied in the 2–300 K region at 2000 G.
