In the title compound, β‐C 5 H 7 N 2 + ·H 2 PO 4 − , the tetrahedral dihydrogenphosphate moieties are linked into double chains by O—H⋯O hydrogen bonds, and the organic species crosslink the chains into sheets by way of N—H⋯O bonds. The resulting structure is quite different from that of the previously described α polymorph of this stoichiometry [Czapla, Dacko & Waskowska (2003). J. Phys. Condens. Matter , 15 , 3793–3803].
