| 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。 | |

| Abstract: 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 AgNO3. The complexes were characterized by elemental analysis, FT-IR, thermo-gravimetrie analysis (TGA) and X-ray single-crystal structure analysis, and fluorescence properties of the complex 2 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 one-dimensional infinite chain is obtained by Ag…Ag interactions. Hydrogen bonding and π…π interactions were observed in these complexes. | |
