外文摘要：Two coordination polymers {[Ag-2(ELBA)(4,4'-bipy)(2)(NO3)]center dot 2H(2)O} (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, thermogravimetrie 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 center dot center dot center dot Ag interactions. Hydrogen bonding and pi center dot center dot center dot pi interactions were observed in these complexes. CCDC: 997226, 1; 997227, 2.
