and electrochemical properties of fluorine-free silver-containing ionic liquids are presented. The ionic liquid cations are formed by a silver(I) ion surrounded by two 1-alkylimidazole ligands, with the counter anions being nitrate ions. Depending on the alkyl chain length, the complexes were found to be liquids at room temperature or melting slightly above this. For the solid compounds it was possible

银(形成我)离子被两个1-烷基
咪唑配体包围,抗衡阴离子为
硝酸根离子。取决于烷基链的长度,发现该络合物在室温下为液体或在此温度以上略微熔化。对于固体化合物,可以通过单晶X射线分析来阐明其结构。
离子液体具有电活性,具有良好的传质性能,可用于高电流密度下电沉积
银。通过差示扫描量热法和热重分析法测试了这些化合物的热性质和稳定性。
离子液体的粘度遵循Vogel–Tamman–Fulcher关系作为温度的函数。
