外文摘要：Three new coordination polymers {[Ag-2(2,4-DCPA)(4,4'-bipy)(2)(NO3)].(H2O)}(n), (1), [Ag(2,4-DCPA)(bpp)](n) (2) and {[Ag(4-DCPA)(bpp)].(H2O)}(n), (3), were synthesized by evaporation methods using 2,4-dichlorophenylacetic acid (2,4-DCPA), 4-chlorophenylacetic acid (4-DCPA), 4,4'-dipyridyl (4,4'-bipy), 1,3-bis(4-pyridyl)propane(bpp) and AgNO3. Compound 1 crystallizes in monoclinic, space group P21/c with a = 10.035(2), b = 17.796(3), c = 16.448(2) angstrom, beta = 104.086(2)degrees, V= 2705.9(2) angstrom(3), D-c, = 1.893 g/cm(-3), C28H23Cl2N5O6Ag2, M-r = 812.15, F(000) = 1608, mu(MoK alpha) = 1.615 mm(-1), Z = 4, R = 0.0310, wR = 0.0832 for 4357 observed reflections (I> 2 sigma(1)), and R = 0.0362, wR = 0.0873 for all data. Compound 2 crystallizes in monoclinic, space group P2(1)/c with a = 9.840(2), b = 24.971(5), c = 9.3301(2) angstrom, beta= 117.504(2)degrees, V= 2033.5(7) angstrom(3), D, = 1.666 g/cm(-3), C21H19C12N2O2Ag, M-r= 510.15, F(000) = 1024, mu(MoK alpha)= 1.273 mm(-1), Z= 4,angstrom R = 0.0315 and wR = 0.0680 for 2853 observed reflections (I> 2 sigma(1)) and R = 0.0454, wR = 0.0736 for all data. Compound 3 crystallizes in monoclinic, space group P2(1)/n with a = 15.472(4), b = 9.000(2), c = 16.262(4)angstrom ,beta = 112.049(4)degrees, V= 2099.0(8) angstrom(3), D, = 1.562 g/cm(3), C(21)H(22)C1N(2)O(3)Ag, M-r = 493.73, F(000) = 1000, mu(MoK alpha) = 1.111 mm(-1), Z = 4, R = 0.0296, wR = 0.0821 for 3059 observed reflections (I> 2 sigma(1)), and R = 0.0398, wR = 0.0986 for all data. The complexes were characterized by elemental analysis, FT-IR, thermogravimetrie analysis (TGA) and X-ray single-crystal structure analysis. Fluorescence properties of complex 3 and PXRD of 1 and 2 have been studied. As a result, in complex 1, the Ag(I) ion is surrounded by two nitrogen atoms from two bipy ligands to form an infinite chain, and adjacent Ag-bipy chains produce "rungs" of a ladder by silver ions contact. And in complexes 2 and 3, the two-dimensional beta-sheet like layers are obtained by Ag-Ag interactions.
