Five new Cd(II) coordination polymers with N-benzoyl-L-glutamic acid (H(2)bzgluO) and different N-donor ligands, [Cd(bzgluO)(2,2'-bipy)(H2O)](n) (1), [Cd(bzgluO)(2,4'-bipy)(2)(H2O)center dot 3H(2)O](n) (2), [Cd(bzgluO) (Phen)center dot H2O](n) (3), [Cd(bzgluO)(4,4'-bipy)(H2O)](n) (4), [Cd(bzgluO)(bpp)(H2O)center dot H2O](n) (5) were synthesized (2,2'-bipy=2,2'-bipyridine, 2,4'-bipy=2,4'-bipyridine, phen=1,10-phenanthroline, 4,4'-bipy=4,4'-bipyridine, bpp=1,3-di(4-pyridyl)propane). Compounds 1-2 exhibit a 1D single-chain structure. Compound 1 generates a 2D supramolecular structure via pi-pi stacking and hydrogen bonding, 3D architecture of compound 2 is formed by hydrogen bonding. Compound 3 features a 1D double-chain structure, which are linked by pi-pi interactions into a 2D supramolecular layer. Compounds 4-5 display a 2D network structure. Neighboring layers of 4 are extended into a 3D supramolecular architecture through hydrogen bonding. The structural diversity of these compounds is attributed to the effect of ancillary N-donor ligands and coordination modes of H(2)bzgluO. Luminescent properties of 1-5 were studied at room temperature. Circular dichroism of compounds 1, 2 and 5 were investigated.
