Abstract
In the title compound, C6H16N4O22+. 2NO(3)(-), the diprotonated argininium molecule is linked by a strong O-H . . .O [2.653 (7) Angstrom] hydrogen bon d to the nitrate anion. The single-bonded O atom of the carboxyl group exhi bits a very unusual cis conformation with respect to the alpha -amino N ato m. Chelated three-centered hydrogen bonds are observed in the case of the N -alpha and N-epsilon atoms with the nitrate anions. The argininium molecule s are connected by type A, B and D interactions through nitrate anions.
