2,6-Diamino­pyridinium dihydrogen phosphate

G. Yu

Abstract: In the crystal structure of the title compound, C5H8N3+·H2PO4-, N-H...O hydrogen bonds, involving the unprotonated amino-group and the NH+ group in the pyridinium ring and dihydrogenphosphate O atoms, link the cations and anions. A long chain-like stacking of dihydrogenphosphate anions along the c-axis direction is constructed by O-H...O hydrogen bonds. Also along the c-axis direction, [pi]-[pi] stacking between inversion-related pyridinium rings [centroid-centroid distance = 3.8051 (10) Å] forms columnar stacks of cations.
