“…These properties infered from the heats, entropies and free energies of solutions of non-polar gases dissolved in EAN. 23 Furthermore, a nearly ideal heat of mixing with water and micelle formation by surfactants dissolved in EAN underline this water-like behavior. 22,24 The interest in ethylammonium nitrate led to the discovery of several protic room temperature ionic liquids, mainly alkylammonium nitrates and thiocyanates.…”

“…35,36 The first true room temperature ionic liquid, ethylammonium nitrate (EAN) was reported in 1914. 1 This polar, colorless liquid exhibits a melting point of 14°C, 22 is supposed to form three-dimensional hydrogen bond networks 23,24 and has an equal number of donor and acceptor sides. In the late Conventional ILs typically contain bulky organic cations with a low degree of symmetry such as imidazolium, pyrrolidinium, tetraalkylphosphonium, trialkylsulfonium or quaternary ammonium.…”

“…EAN facilitates multiple HB opportunities and thus is capable of forming a complex network structure, which has been discussed to be comparable to that of water [5,58]. There exist three acceptor oxygen atoms per anion and three donor positions per cation, so that in principle a fully saturated HB network is possible.…”

Abstract. The properties of the hydrogen bonds in ethylammonium nitrate are analyzed by using molecular dynamics simulations and infrared as well as nuclear magnetic resonance experiments. Ethylammonium nitrate features a flexible three-dimensional network of hydrogen bonds with moderate strengths, which makes it distinct from related triethylammonium-based ionic liquids. First, the network's flexibility is manifested in a not very pronounced correlation of the hydrogen bond geometries, which is caused by rapid interchanges of bonding partners. The large flexibility of the network leads to a substantial broadening of the mid-IR absorption band, with the contributions due to N-H stretching motions ranging from 2800 to 3250 cm −1 . Finally, the different dynamics are also seen in the rotational correlation of the N-H bond vector, where a correlation time as short as 16.1 ps is observed.

“…A range of models have been used to describe IL bulk structure, including ion pairs, [3][4][5][6] hydrogen-bonded networks, [7][8][9][10][11][12][13][14][15][16] ion clusters, [17][18][19] and self-assembled nanoscale structuring. 1,[20][21][22][23][24][25][26][27][28][29] The most appropriate model is strongly related to the type of IL under study, as there are many distinct classes.…”
