Reaction stoichiometry, dynamic light scattering, and DFT are used to explore tertiary ammonium bicarbonates that exist as ideal solutes and those that self-assemble. Self-assembling tertiary amines featured organic surfaces beyond a through-space defined sphere around the charge center. Like-charge hydrogen-bonded ion pairs (or anti-electrostatic hydrogen bonding (AEHB)) also play a role in the self-assembly and provide the first evidence of this bonding motif by bicarbonate in aqueous solution. A single crystal neutron structure of a tertiary ammonium bicarbonate featuring a bicarbonate dimer is presented.

通过类似电荷的离子相互作用和通过空间定义的有机域自组装分子离子

反应化学计量，动态光散射和DFT用于研究碳酸叔叔碳酸氢盐，它们以理想的溶质形式存在，并且可以自组装。自组装叔胺的特征是有机表面超出了围绕电荷中心的贯穿空间的范围。电荷相同的氢键离子对（或抗静电氢键（AEHB））在自组装中也起作用，并通过水溶液中的碳酸氢盐提供了该键基序的第一个证据。提出了具有碳酸氢盐二聚体的碳酸氢叔铵的单晶中子结构。
