  the carbonyl solvent molecules (DMF, DEF, DMA, and NMP) can affect the coordination geometries around the La(III) ions, the coordination modes of carboxylate groups, the packing arrangements, and the void volumes of the overall crystal lattices. One as-synthesized framework further shows an unprecedented structural transformation from a 3D 6-connected network to a 3D 4,5-connected net through the dissolution

  利用四氯化苯二羧酸配体的一系列位置异构体，溶剂热合成了七个基于La（III）的配位聚合物并对其结构进行了表征。它们的结构尺寸从1D双链到2D 3,4,5-连接的网络，再到3D 6连接的pcu拓扑网不等，仅受四氯化苯环上羧基的位置支配。全面的分析和比较表明，羰基溶剂分子（DMF，DEF，DMA和NMP）的大小会影响La（III离子，羧酸根基团的配位方式，堆积安排以及整个晶格的空隙体积。一个合成的框架进一步表明，通过在水中的溶解和重整途径，可以从3D 6连接网络到3D 4,5连接网络进行前所未有的结构转换，这表明这些易水解的镧系元素络合物可以作为生产新的镧系元素的前体。高维框架。利用这些La（III作为引发剂的复合物是本文首次报道。发现所有络合物均可在200至220°C的温度范围内促进乙交酯的聚合反应，产生分子量高达93 280的聚乙醇酸（PGA）。在相同的实验条件下，不同的催化活性这些复合物可能是由于它们的结构差异造成的。
