Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The coordination polymers, {[Cu(Hbidc)(2, 2′‐bpy)(H₂O)]<bold>·</bold>2H₂O}<italic>_n</italic> (<bold>1</bold>) and {[Mn(Hbidc)(2, 2′‐bpy) (H₂O)₂]<bold>·</bold>2H₂O}<italic>_n</italic> (<bold>2</bold>) (H₃bidc = benzimidazole‐5, 6‐dicarboxylic acid, 2, 2′‐bpy = 2, 2′‐bipyridine), were synthesized in solution and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis (TGA), and single‐crystal X‐ray diffraction. Complexes <bold>1</bold> and <bold>2</bold> consist of different 1D chain structures. In both compounds, 2, 2′‐bpy is chelating in a bidentate manner, whereas the Hbidc ligands in complexes <bold>1</bold> and <bold>2</bold> display chelating‐bridging tridentate and bridging bidentate coordination modes. The two complexes are further extended into 3D supramolecular structures through O–H<bold>···</bold>O and N–H<bold>···</bold>O hydrogen bonds. The thermal stabilities of complexes <bold>1</bold> and <bold>2</bold> were studied by thermogravimetric analyses (TGA).</p> </abstract>
