本文合成了1个二维层状磺酸银配位聚合物[Ag2(HL)(MeCN)]n,(H3L=2-羟基-3-羧基-5-溴苯磺酸),并且进行了元素分析、红外、热重、荧光、粉末及单晶X射线衍射等表征及研究.标题化合物属于三斜晶系,空间群P(1),a=0.702 71(14) nm,b=0.828 98(17) nm,c=1.233 1(3) nm,α=84.32(3)°,β=73.90(3)°,γ=67.26(3)°,V=0.636 5(2) nm3,Z=2,R=0.0565.Ag1离子分别与来自3个不同HL2-配体的4个氧原子和1个乙腈分子中的氮原子配位,展示出扭曲的四方锥几何构型,而Ag2离子则分别与来自4个不同HL2-配体的6个氧原子配位,展示出扭曲的八面体几何构型.相邻的银离子间通过磺酸基氧原子、羟基氧原子连接形成一维带状结构,该一维带进一步通过羧基氧桥联成二维层状结构.此外,该配合物在室温下具有较强的蓝光发射峰.%A 2D coordination polymer, [Ag2(HL)(MeCN)]n (H3L=2-hydroxy-3-carboxy-5-bromobenzenesulfonic acid, has been synthesized and characterized by elemental analysis, IR, TG, PL, powder and X-ray single crystal diffraction. The title complex crystallized in triclinic with space group PI, a=0.702 71(14) nm, 6=0.828 98(17) nm, c=1.233 1(3) nm, α=84.32(3)°, β=73.90(3)°, γ=67.26(3)° and V=0.6365(2) nm3, Z=2, K =0.056 5. Agl ion is five-coordinated by four oxygen atoms from three different HL2- groups and one coordinated acetonitrile molecule to complete a distorted square-pyramidal geometry, while Ag2 ion exists in a distorted octahedron defined by six oxygen atoms from four different HL2" groups. The oxygen atoms from sulfonate and hydroxyl groups link adjacent Ag(I) ions to form ID chains, which are further linked into 2D layer through carboxyl groups. In addition, this complex exhibits strong blue emission at room temperature. CCDC: 832874.
