作为用阳离子敏感玻璃电极研究乙腈中一价阳离子与其它溶剂络合作用的一部分，研究了乙腈中铵离子与水、甲醇、N-甲基甲酰胺、N，N-二甲基甲酰胺、N，N-二甲基乙酰胺、二甲亚砜、1-甲基-2-吡咯烷酮和六甲基磷酰三胺等溶剂的络合作用，以及二苯并-18-冠-6。在研究络合之前，阳离子敏感玻璃电极被证实以能斯特方式响应于由于溶剂的变化而发生的铵离子活性的变化（溶剂效应）。乙腈中的铵离子与甲醇和水形成单溶剂化和双溶剂化物种的络合物。用DMF、DMA和DMSO形成高达三溶剂化物质的形式，并且用1-甲基-2-吡咯烷酮和NMF形成高达四溶剂化物质的形式。使用HMPA，甚至形成五溶剂化物质。复杂的结构…
As a part of potentiometric studies of the complexing of univalent cations in acetonitrile with other solvents by the use of a cation-sensitive glass electrode, investigations were carried out of the complexing of the ammonium ion in acetonitrile with such solvents as water, methanol, N-methylformamide, N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide, 1-methyl-2-pyrrolidone, and hexamethylphosphoric triamide, and also with dibenzo-18-crown-6. Prior to the study of the complexing, the cation-sensitive glass electrode was confirmed to respond in a Nernstian way to the change in the ammonium-ion activity which occurs due to the change of the solvent (solvent effect). The ammonium ion in acetonitrile formed complexes of mono- and di-solvated species with methanol and water. Formations of up to tri-solvated species were formed with DMF, DMA, and DMSO, and up to tetra-solvated species with 1-methyl-2-pyrrolidone and NMF. With HMPA, even penta-solvated species were formed. The complex formation ...
