Two new Ag(I) complexes {Ag2(L)(NO3)(H2O)}n(1) and {Ag(L)}n·nH2O(2) have been synthesized via the reaction of silver nitrate and betaine derivative 1-carboxymethylpyridinium-3-carboxylate(L) by only changing the metal-to-ligand ratio. The results of X-ray crystallographic analysis indicate that complexes 1 and 2 both crystallize in the monoclinic space group P21/c with a = 5.0809(14), b = 17.390(5), c = 13.399(4), β = 91.677(5)o, V = 1183.4(6)3, Z = 4, Mr = 475.90, Dc = 2.671 g/cm3, F(000) = 912, μ = 3.352 mm-1, S = 1.259, the final R = 0.0320 and wR = 0.0831 for 2036 observed reflections with I > 2σ(I) for 1 and a = 12.180(2), b = 5.0283(10), c = 14.396(3), β = 94.87(3)o, V = 878.5(3)3, Z = 4, Mr = 306.02, Dc = 2.314 g/cm3, F(000) = 600, μ = 2.294 mm-1, S = 1.053, the final R = 0.0283 and wR = 0.0684 for 2011 observed reflections with I > 2σ(I) for 2. Complexes 1 and 2 both feature a unique 2D structure. For 1, the 2D undulated network consists of 1D infinite helical chains running parallel to the b axis, while for 2, the 2D network is made up of 1D tubes along the b axis. Moreover, the Ag…Ag interactions in complexes 1 and 2 are also discussed.
