formation of dimers, while the silver(I) complex shows polymerization associated with the O atoms of three distinct deprotonated ligands (L−). Thus, the structure of the Ag complex can be considered as a coordination polymer consisting of a one‐dimensional linear chain, constructed by carboxylate bridging groups, running parallel to the b axis. Neighbouring polymeric chains are further bridged by Ag—C
在目前的工作中,两维(2D)聚合物聚[[μ 4 -2-(4-硝基苯磺酰氨基)benzoato-κ 4 ø 1:Ò 1:Ö 1' :Ñ 6 ]银(I)](银L)[Ag(C 13 H 9 N 2 O 6 S)] n是从2-(4-硝基苯磺酰胺基)苯甲酸(H L),C 13 H 10 N 2 O 6 S获得的。FT-IR,1 H和13 C 11 H NMR光谱分析用于表征两种化合物。H L和Ag L的晶体结构是通过单晶X射线衍射确定的。在H的结构大号,O - H ...相邻分子O之间的氢键导致二聚体的形成,而银(I)络合物展示聚合用的三种不同的去质子化的配体(O原子关联大号- )。因此,Ag络合物的结构可以被认为是由一维线性链组成的配位聚合物,该线性链由羧基桥接基团构成,并平行于b轴。相邻的聚合物链进一步通过Ag-C单价接触桥接,形成2D框架。Hirshfeld表面的指纹分析表明,O…H / H…O氢键是H
