| 摘要: 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。 |

| Abstract: An acylhydrazone-type Schiff base ligand (NaL) was synthesized by reaction of sodium 2-formylbenzene sulfonate with isoniazide in a mixture of ethanol and water. A Zn(Ⅱ) coordination polymer {[Zn(L)2(H2O)2]·4H2O}n have been synthesized by employing the solution preparation method at room temperature and characterized by elemental analysis, IR, TGA and X-ray diffraction structural analysis. Crystal data: triclinic system, space group P1, 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. Each Zn(Ⅱ) ion is bridged by two L- ligands in the monodentate-monodentate mode to form a ring-like dimer units, and a one-dimensional chain is built by sharing a Zn(Ⅱ) ion between the units. The adjacent chains are linked into a 3D supramolecular network structure via hydrogen bonds and π-π interactions with a 1D open channel that are occupied by solvent molecules. CCDC: 934292. |
