Abstract: The 4-phenylpyridinium cation of the title compound, C₁₁H₁₀N⁺·C₄HO₄^-, exhibits an interplanar angle of 28.6 (1)° and interacts with a neighbouring hydrogensquarate anion through a single N-HO hydrogen bond [NO = 2.697 (2) Å]. Individual anions are linked into centrosymmetric dimers by strong O-HO hydrogen bonds [HO = 1.52 Å and OO = 2.493 (2) Å]. Alternating layers of 4-phenylpyridinium cations and hydrogensquarate anions are stacked along the [001] axis.
