organic compounds
In the title compound, C4H8N3O+·NO3-, creatininium cations and nitrate anions are linked to each other through strong hydrogen bonds, formed by all H atoms covalently bonded to the N atoms. Short contacts are also observed between the anions. This complex three-dimensional network of hydrogen bonds ensures the cohesion of the ionic structure.
organic compounds
The crystal structure of DL-2-ammonium-4-methylvaleric acid nitrate (C6H14NO2+·NO3-, DL-leucinium nitrate) can be described by considering two types of layers parallel to the bc plane: hydrophilic layers including the head of the leucinium residue (ammonium and carboxylic groups) with the nitrate anion, and hydrophobic layers including the tail of the leucinium residue.
