摘　　要：Two new coordination polymers based on 4-[（8-hydroxy-5-quinolinyl）azo]-benzenesulfonic acid（H2L）,{[CdL（H2O）2]·H2O}n（1） and {[CdL（en）]·EtOH}n（2）（en=ethylenediamine）,were solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction.Compounds 1 and 2 exhibit infinite 1D ladder-shaped chain structures,which are isostructural except that the two coordinating water molecules in compound 1 were replaced by one en molecule in compound 2 due to the use of different organic base.Compounds 1 and 2 were constructed into different supramolecular frameworks by hydrogen bonding and π…π stacking interactions.In addition,the fluorescent properties of compounds 1 and 2 were investigated.Furthermore,they were also investigated via IR spectral analysis,elemental analysis,powder X-ray diffraction（PXRD） and thermogravimetric analysis（TGA）.Two new coordination polymers based on 4-[（8-hydroxy-5-quinolinyl）azo]-benzenesulfonic acid（H2L）,{[CdL（H2O）2]·H2O}n（1） and {[CdL（en）]·EtOH}n（2）（en=ethylenediamine）,were solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction.Compounds 1 and 2 exhibit infinite 1D ladder-shaped chain structures,which are isostructural except that the two coordinating water molecules in compound 1 were replaced by one en molecule in compound 2 due to the use of different organic base.Compounds 1 and 2 were constructed into different supramolecular frameworks by hydrogen bonding and π…π stacking interactions.In addition,the fluorescent properties of compounds 1 and 2 were investigated.Furthermore,they were also investigated via IR spectral analysis,elemental analysis,powder X-ray diffraction（PXRD） and thermogravimetric analysis（TGA）.
