Abstract

In the title compound, C3H5N2+·C2HO4−, the anions form centrosymmetric dimers through cyclic O—H⋯O hydrogen-bonding associations [graph set R22(10)]. These dimers are then linked through a cyclic R42(10) N—H⋯O hydrogen-bonding association involving two cations and the carboxyl O-atom acceptors of separate anions, giving chain structures extending across the (111) plane.
