Abstract: Solvothermal reactions of cadmium salts with bipyridyl diene and triene ligands[1,3-bis((E)-2-(pyridin-4-yl)vinyl)benzene-(1,3-bpeb) and 1,6-bis(4-pyridyl)-1,3,5-hexatriene(bphte)] and one bipyridyl triene ligand[1,6-bis(4-pyridyl)-1,3,5-hexatriene-(bphte)] in the presence of auxiliary carboxylic acids including 2,6-dichlorobenzoic acid(2,6-HDCBA) and 2-naphthal-enecarboxylic acid(2-HNCA) gave rise to four coordination polymers[Cd(bphte)(2,6-DCBA)2]n(1), {[Cd(bphte)(2-NCA)2]·5.8H2O}n(2),[Cd2(1,3-bpeb)2(2,6-DCBA)4]n(3) and {[Cd4(1,3-bpeb)4(2-NCA)7(HCOO)]·

2-HNCA·H2O}n(4), respectively. Compounds 1-4 were structurally characterized by elemental analysis, IR, 1H NMR, powder X-ray diffraction, thermogravimetric analysis and single-crystal X-ray diffraction. They possess one-dimensional linear(1, 2) and zigzag(3, 4) chain structures. Their luminescent properties were explored while the representative sample 4 exhibited good luminescent performance in sensing Fe(III) in water.

Key words: Coordination polymer, Bipyridyl olefinic ligand, Crystal structure, Luminescent property
