A metal-organic supramolecular polymer [Zn5(D,L-Alaninato)4(Terephthalate)3]n(1) was obtained under hydrothermal conditions by the reaction of D,L-alanine and terephthalic acid with Zn(NO3)2·6H2O.In the structure,Zn(II) ions interact with terephthalic acid to form 2D metal-organic coordination layer framework and alanine anions bridge Zn(II) centers into 1D chain-like structure.A 3D supramolecular framework results from bridging carboxylic group of amino acid which connects coordination layer and chain together.%以D,L-丙氨酸(D,L-Alanine)和对苯二甲酸(Terephthalic acid)为有机配体,与硝酸锌在水热条件下反应得到了金属-有机超分子聚合物[Zn5(D,L-Alaninato)4(Terephthalate)3]n(1).在该化合物中,Zn(Ⅱ)离子与对苯二甲酸相互作用形成了二维的金属-有机配位层状框架,丙氨酸桥联Zn(II)离子形成了一维的配位链状结构.配位层与配位链之间通过氨基酸的桥联作用连接在一起形成了三维的超分子框架结构.
