Three new coordination polymers {[Ag2(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) Å, β = 104.086(2)º, V = 2705.9(2) Å3, Dc = 1.893 g/cm-3, C28H23Cl2N5O6Ag2, Mr = 812.15, F(000) = 1608, μ(MoK) = 1.615 mm-1, Z = 4, R = 0.0310, wR = 0.0832 for 4357 observed reflections (I > 2σ(I)), and R = 0.0362, wR = 0.0873 for all data. Compound 2 crystallizes in monoclinic, space group P21/c with a = 9.840(2), b = 24.971(5), c = 9.3301(2) Å, β = 117.504(2)º, V = 2033.5(7) Å3, Dc = 1.666 g/cm-3, C21H19Cl2N2O2Ag, Mr = 510.15, F(000) = 1024, μ(MoK) = 1.273 mm-1, Z = 4, R = 0.0315 and wR = 0.0680 for 2853 observed reflections (I > 2σ(I)) and R = 0.0454, wR = 0.0736 for all data. Compound 3 crystallizes in monoclinic, space group P21/n with a = 15.472(4), b = 9.000(2), c = 16.262(4) Å, β = 112.049(4)º, V = 2099.0(8) Å3, Dc = 1.562 g/cm-3, C21H22ClN2O3Ag, Mr = 493.73, F(000) = 1000, μ(MoK) = 1.111 mm-1, Z = 4, R = 0.0296, wR = 0.0821 for 3059 observed reflections (I > 2σ(I)), 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 β-sheet like layers are obtained by Ag···Ag interactions.
