Two novel metal–organic coordination polymers, [Cd(bqdc)(phen) 2 ] n ( 1 ), [Cd(bqdc)(phen)] n ( 2 ), (H 2 bqdc = 2,2′‐biquinoline‐4,4′‐dicarboxylic acid, phen = 1,10‐phenanthroline) were obtained with different metal/ligand ratios through hydrothermal method. Their structures were determined by single‐crystal X‐ray diffraction. In two complexes, central Cd 2+ ions and (bqdc) 2− ligands display completely different coordination modes. 1 is a 1‐D zigzag chain, two phen ligands chelate to one cadmium atom, which is rare in similar polymers. 2 is a 3‐D framework, exhibits an unusual eight‐coordinate structure (CdN 2 O 6 ) and the coordination polyhedron can be described as distorted monocapped pentagonal bipyramid. 1 and 2 are stable in air, and show blue photoluminescence at room temperature.
