Abstract Two coordination polymers, namely [Cd(HL) 2 ] n · n H 2 O ( 1 ) and [Zn(L)] n ( 2 ) (H 2 L = benzimidazole‐2‐butanoic acid), were prepared by solvothermal reaction of Cd(NO 3 ) 2 or Zn(NO 3 ) 2 and H 2 L. The structures of these two compounds were determined by the single‐crystal X‐ray diffraction analyses and further characterized by IR spectroscopy, elemental analyses, powder X‐ray diffraction analyses, and thermal analyses. Compound 1 is a two‐dimensional (2D) layer framework, which is further packed into a 3D supramolecular framework by intermolecular hydrogen bonds, whereas compound 2 is a three‐dimensional (3D) framework with 3‐connected etb topology. The H 2 L ligand in compounds 1 and 2 displays two different anionic forms (HL – and L 2– ), which then adopt two different coordination modes. Moreover, thermal stabilities and luminescent properties of these two compounds were also investigated.
