2-(2-Pyridylamino)pyridinium nitrate monohydrate: two-dimensional supramolecular aggregation through hydrogen-bonding and - stacking interactions

M. Du and X.-J. Zhao

Abstract: In the crystal structure of the title compound, C₁₀H₁₀N₃⁺·NO₃^-·H₂O, (I), the asymmetric unit contains two crystallographically independent but similar subunits. The protonated C₁₀H₁₀N₃⁺ cation adopts the normal trans-trans configuration and approximately planar geometry. Multiple hydrogen-bonding interactions expand the structure, resulting in a two-dimensional layered architecture, which is further stabilized by aromatic - stacking interactions between the protonated cations.
