Four Ln ‐NDC coordination polymers [ Ln (NDC)(HNDC)(H 2 O)] ( Ln = La ( 1 ), Pr ( 2 ), Nd ( 3 ), Sm ( 4 ), H 2 NDC = 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 NDC 2– ligand, in which the H 2 NDC ligands adopt two different acidity‐dependent types and coordination modes: HNDC 1– with μ‐η 1 :η 1 and NDC 2– with μ‐η 1 :η 2 :η 1 :η 2 . 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 Ln III ions. In addition, thermogravimetric analysis of compound 2 is described.
