Popis:	Two novel metal–organic coordination polymers, [Cd(bqdc)(phen)2]n (1), [Cd(bqdc)(phen)]n (2), (H2bqdc = 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 Cd2+ 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 (CdN2O6) 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.
