本文以6,6′-二硫二烟酸为主配体,通过水热法合成了新的配合物{[Zn(cpds)(dpa)]·H2O}n(1)(H2cpds=6,6′-dithiodinicotinic acid,dpa=dipyridin-2-ylamine)。用X-射线单晶衍射分析确定了配合物为三斜晶系,P1空间群,其晶体学参数为a=0.846 7(2),b=1.167 4(3),c=1.226 5(3)nm,α=73.605(3)°,β=78.656(3)°,γ=81.484(3)°,V=1.134 7(5)nm3,Dc=1.850 g·cm-3,Z=2。结构分析表明配合物1为一维链状结构,相邻一维链之间堆积形成三维超分子网络结构。本文还研究了配合物的热稳定性和荧光性质。
In this paper, a new complex {[Zn (cpds) (dpa)] · H2O} n (1) (H2cpds = 6,6 ’-dithiodinicotinic acid, dpa = dipyridin-2-ylamine). The crystal structure of the complex is triclinic and P1 space group. The crystallographic parameters are a = 0.846 7 (2), b = 1.167 4 (3), c = 1.226 5 (3) nm, α = 73.605 (3) °, β = 78.656 (3) °, γ = 81.484 (3) °, V = 1.134 7 (5) nm3, Dc = 1.850 g · cm-3, and Z = Structural analysis shows that complex 1 is a one-dimensional chain structure, and three-dimensional supramolecular network structure is formed by stacking between adjacent one-dimensional chains. The thermal stability and fluorescence properties of the complexes were also studied.
