R. Ittyachan, P. Sagayaraj and B. Kothandapani

Abstract: In the crystal structure of the title compound, C₆H₁₆N₄O₂²⁺·2H₂PO₄^-, the argininium residue has a gauche II-trans-trans-trans conformation. The argininium residue forms N-HO and O-HO hydrogen bonds with the phosphate anions; the latter form O-HO hydrogen bonds with each other. Three-centered hydrogen bonding is also observed.
