以邻甲酰基苯磺酸钠和异烟肼为原料在乙醇/水溶液中制备了一种酰腙类Schiff碱配体(NaL),采用常规溶液挥发法合成了由该配体构筑的Zn((Ⅱ)配位聚合物{[Zn(L)2(H2O)2]·4H2O}n。利用元素分析、IR、TGA和X-射线单晶衍射分析对配合物进行了表征。配合物晶体属三斜晶系,P1空间群,晶胞参数a=0.786 98(4)nm,b=0.869 26(5)nm,c=1.180 44(7)nm,α=103.353(5)°,β=100.965(4)°,γ=93.123(4)°,Z=1,V=0.767 24(7)nm3,Dc=1.697 g·cm-3。每个Zn(Ⅱ)离子被2个配体L-阴离子双重桥联形成二核环状结构单元,并通过共用锌离子形成一维链配位聚合物,链与链之间通过氢键扩展为具有一维开放孔道的三维超分子网络结构。
An acylhydrazone Schiff base ligand (NaL) was prepared from sodium ortho-formylbenzenesulfonate and isoniazid in ethanol / water solution. The Zn (( The complex was characterized by elemental analysis, IR, TGA and X-ray single crystal diffraction analysis. The complex crystal belongs to the complex of three [Zn (L) 2 (H2O) 2] A = 103.353 (5) °, β = 100.965 (b), a = 0.186 98 (4) nm, b = 0.869 26 4) °, γ = 93.123 (4) °, Z = 1, V = 0.767 24 (7) nm3, Dc = 1.697 g · cm-3. Each Zn (Ⅱ) Bridged to form a dinuclear cyclic structure unit and formed a one-dimensional chain coordination polymer by sharing zinc ions, and the chain and the chain are expanded to a three-dimensional supramolecular network structure with one-dimensional open pores by hydrogen bonding.
