Synthesis and Crystal Structure of a Two-dimensional Cadmium（Ⅱ） Coordination Polymer:[Cd（AIP）（Bpy）]_n·nBpy（H₂AIP=5-Aminoisophthalic Acid, Bpy=2,2′-Bipyridyl）

【摘要】 A two-dimensional coordination polymer, [Cd(AIP)(Bpy)]n·nBpy, was hydrother- mally synthesized by the reaction of hydrate cadmium acetate with 5-aminoisophthalic acid, lithium hydroxide, vanadiumpentoxide, sodium chloride and 2,2′-bipyridyl in water solution. It crystallizes in orthorhombic, space group C2221, absolute structure parameter 0.00(7), with a = 15.336(4), b = 22.390(6), c = 14.257(3) , V = 4896(2)3, C28H21CdN5O4, Mr = 603.90, Z = 8, F(000) = 2432, Dc = 1.639 g/cm3, μ = 0.939 mm–1, T = 298(2) K, S = 1.001, R = 0.0296 and wR = 0.0813 for 5522 observed reflections (I > 2σ(I)). In the title complex, each 5-aminoisophthalate ligand bridges three cadmium(II) ions to form a two-dimensional layer structure.更多还原
