In poly[aqua(μ 3 ‐benzene‐1,4‐dicarboxylato‐κ 5 O 1 , O 1′ : O 1 : O 4 , O 4′ )[2‐(pyridin‐3‐yl‐κ N )‐1 H ‐benzimidazole]cadmium(II)], [Cd(C 8 H 4 O 4 )(C 12 H 9 N 3 )(H 2 O)] n , (I), each Cd II ion is seven‐coordinated by the pyridine N atom from a 2‐(pyridin‐3‐yl)benzimidazole (3‐PyBIm) ligand, five O atoms from three benzene‐1,4‐dicarboxylate (1,4‐bdc) ligands and one O atom from a coordinated water molecule. The complex forms an extended two‐dimensional carboxylate layer structure, which is further extended into a three‐dimensional network by hydrogen‐bonding interactions. In catena ‐poly[[diaquabis[2‐(pyridin‐3‐yl‐κ N )‐1 H ‐benzimidazole]cobalt(II)]‐μ 2 ‐benzene‐1,4‐dicarboxylato‐κ 2 O 1 : O 4 ], [Co(C 8 H 4 O 4 )(C 12 H 9 N 3 ) 2 (H 2 O) 2 ] n , (II), each Co II ion is six‐coordinated by two pyridine N atoms from two 3‐PyBIm ligands, two O atoms from two 1,4‐bdc ligands and two O atoms from two coordinated water molecules. The complex forms a one‐dimensional chain‐like coordination polymer and is further assembled by hydrogen‐bonding interactions to form a three‐dimensional network.
