Abstract
A crystallographic investigation of the 2,4,6-trihydroxybenzene-1,3,5-trisulfonic acid ligand (H6L) with various cations was conducted. The melamine adduct exhibited an H-bonded three-dimensional lattice (1), guanidine incorporation resulted in the formation of a two-dimensional (2D) layer (2) with unusual loss of aromaticity of the ligand and reaction with potassium ion afforded a three-dimensional (3D) network (3) with channels that possessed an H-bonded water chain. The proton conductivity of 3 was 2.61 × 10−7 S cm−1 at room temperature, indicating its potential application in proton-conducting materials.
对不同阳离子的2,4,6-三羟基苯-1,3,5-三磺酸配体(H6L)进行了晶体学研究。三聚氰胺加合物表现出h键三维晶格(1),胍的掺入导致形成二维(2D)层(2),配体芳香性异常丧失,与钾离子反应形成三维(3D)网络(3),其通道具有h键水链。在室温下,3的质子电导率为2.61 × 10−7 S cm−1,表明其在质子导电材料中的应用潜力。
