Crystal structure of the ionic liquid EtNH3NO3—Insights into the thermal phase behavior of protic ionic liquids

Author affiliations

Abstract

The crystal structure of the salt ethylammonium nitrate (EtNH3NO3) has been determined. EtNH3NO3 is one of the most widely studied protic ionic liquids (PILs)—ILs formed by proton transfer from a Brønsted acid to a Brønsted base. The structural features from the crystal structure, in concert with a Raman spectroscopic analysis of the ions, provide direct insight as to why EtNH3NO3 melts below ambient temperature, while other related salts (such as EtNH3Cl) do not.
