摘　　要：以2,4-二氯苯氧乙酸、2,2′-联吡啶、4,4′-联吡啶和硝酸银为原料,采用自然挥发法制备了2个配合物{[Ag2(ELBA)(4,4′-bipy)2(NO3)]·2H2O}n(1)和[Ag2(ELBA)2(2,2′-bipy)]n(2)(ELBA=2,4-二氯苯氧乙酸,4,4′-bipy=4,4′-联吡啶,2,2′-bipy=2,2′-联吡啶),并对其进行了元素分析、红外光谱、热稳定性和X-射线单晶衍射的表征,研究了配合物2的荧光性质。结果表明,配合物1和2均为一维结构,其中,配合物1是通过4,4′-联吡啶和银离子间的作用形成梯状结构;而配合物2是通过Ag…Ag作用构筑S状结构。配合物中存在氢键和π-π堆积等弱的分子间作用力。Two coordination polymers {[Ag2（ELBA）（4,4′-bipy）2（NO3）]·2H2O}n（1） and [Ag2（ELBA）2（2,2′-bipy）]n（2）were synthesized by evaporation methods using 2,4-dichlorophenoxyacetic acid（ELBA）, 4,4′-dipyridyl（4,4′-bipy）,2,2′-dipyridyl（2,2′-bipy） and Ag NO3. The complexes were characterized by elemental analysis, FT-IR, thermogravimetrie analysis（TGA） and X-ray single-crystal structure analysis, and fluorescence properties of the complex2 have been studied. As a result, complexes 1 and 2 are one-dimensional structure. Among others, in complex 1,Ag（Ⅰ） ion is surrounded by two nitrogen atoms from two bipy ligands form an infinite chain, and adjacent Ag-bipy chains produce ＂rungs＂ of a ladder by silver ions contacts. And in compound 2, the similar S-shape onedimensional infinite chain is obtained by Ag … Ag interactions. Hydrogen bonding and π … π interactions were observed in these complexes.
