Syntheses and Crystal Structures of Two New Ag(Ⅰ) Complexes with Betaine Derivative: Structure Changes via Metal-to-ligand Ratio
摘要:
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)Å, β=91.677(5)°, V=1183.4(6)Å3, 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)Å, β=94.87(3)°, V=878.5(3)Å3, 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.
