Bottom Line: The anion chains are connected by water mol-ecules, which lie on crystallographic twofold rotation axes, through O-H⋯O hydrogen bonds.These hydrogen bonds are almost perpendicular to the other hydrogen bonds which create an assembled structure of anions.In addition, C-H⋯O hydrogen bonds between anions and cations are observed.

ABSTRACT
In the crystal structure of the title compound, C(4)H(12)N(+)·H(2)PO(4) (-)·0.5H(2)O, the anions form an infinite hydrogen-bonded chain along the [10] direction. The anion chains are connected by water mol-ecules, which lie on crystallographic twofold rotation axes, through O-H⋯O hydrogen bonds. These hydrogen bonds are almost perpendicular to the other hydrogen bonds which create an assembled structure of anions. In addition, C-H⋯O hydrogen bonds between anions and cations are observed.
