报道了一个基于柔性三硫醚配体(L=1 ,3,5 -三(苯基硫代亚甲基) - 2 ,4,6-三甲基苯)的新型Ag 配合物{[Ag3 (L ) 2 (Cl O4) 2 ](Cl O4) }∞(1 )的合成与结构表征.X-射线单晶衍射结果表明,配合物1为单斜晶系,C2 /c空间群,晶胞参数为a=3.4931 (7) nm,b=2 .1 5 84(8) nm,c=2 .8782 (4)nm,β=1 2 3.688(1 0 ) o,V=1 8.0 5 6(3) nm3 ,Z=8.配合物1的不对称单元中存在3个晶体学独立的Ag 离子,其中一个为四配位,另外两个具有线性二配位模式.每个配体中的3个硫原子通过与其邻近的3个Ag 离子配位,形成由6个金属离子和6个配体所组成的六边形48元大环重复单元,并且通过这种重复单元构成具有(6,3)拓扑结构的二维无限蜂窝状配位网络
A novel Ag complex based on a flexible trisulfide ligand (L = 1, 3,5 - tris (phenylthiomethylene) -2,2,6-trimethylbenzene) The results of X-ray single crystal diffraction show that the complex 1 is monoclinic, C2 / c space group, unit cell The parameters are a = 3.4931 (7) nm, b = 2.1584 (8) nm, c = 2.7882 nm, β = 1 2 3.688 (10) o, V = 1 8.05 6 ( 3) nm3, Z = 8. There are three crystallographically independent Ag ions in the asymmetric unit of complex 1, one of which is tetracoordinated and the other two have a linear two-coordinate mode. A sulfur atom forms a hexagonal 48-membered macrocyclic repeating unit composed of six metal ions and six ligands by coordinating with three adjacent Ag ions, and by this repeating unit, ) Topological structure of two-dimensional infinite honeycomb coordination network
