| Abstract: | Four Ln‐NDC coordination polymers [Ln(NDC)(HNDC)(H2O)] (Ln = La ( 1 ), Pr ( 2 ), Nd ( 3 ), Sm ( 4 ), H2NDC = 1,4‐naphthalenedicarboxylic acid) were hydrothermally synthesized and structurally characterized by elemental analyses, IR spectroscopy, and single‐crystal X‐ray diffraction. Compounds 1 – 4 are isomorphous, and their structures display a layer constructed from a Ln‐organic chain and NDC2– ligand, in which the H2NDC ligands adopt two different acidity‐dependent types and coordination modes: HNDC1– with μ‐η1:η1 and NDC2– with μ‐η1:η2:η1:η2. The 3D supramolecular networks of 1 – 4 are mainly controlled by hydrogen bonds interactions. The magnetic susceptibilities of complexes 2 – 4 reveal overall antiferromagnetic interactions between the LnIII ions. In addition, thermogravimetric analysis of compound 2 is described. |
