Description:
The coordination polymers, {[Cu(Hbidc)(2, 2′-bpy)(H 2 O)] · 2H 2 O} n ( 1 ) and {[Mn(Hbidc)(2, 2′-bpy) (H 2 O) 2 ] · 2H 2 O} n ( 2 ) (H 3 bidc = 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 1 and 2 consist of different 1D chain structures. In both compounds, 2, 2′-bpy is chelating in a bidentate manner, whereas the Hbidc ligands in complexes 1 and 2 display chelating-bridging tridentate and bridging bidentate coordination modes. The two complexes are further extended into 3D supramolecular structures through O–H ··· O and N–H ··· O hydrogen bonds. The thermal stabilities of complexes 1 and 2 were studied by thermogravimetric analyses (TGA).
