Five new Cd(II) coordination polymers with N-benzoyl-L-glutamic acid (H₂bzgluO) and different N-donor ligands, [Cd(bzgluO)(2,2′-bipy)(H₂O)]_n (1), [Cd(bzgluO)(2,4′-bipy)₂(H₂O)·3H₂O]_n (2), [Cd(bzgluO)(phen)·H₂O]_n (3), [Cd(bzgluO)(4,4′-bipy)(H₂O)]_n (4), [Cd(bzgluO)(bpp)(H₂O)·2H₂O]_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 π–π 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 π–π 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 H₂bzgluO. Luminescent properties of 1–5 were studied at room temperature. Circular dichroism of compounds 1, 2 and 5 were investigated.
