The structure of the title compound, 2C(4)H(9)N(2)O(3)(+).C(2)O(4)(2-), which has been determined by X-ray diffraction, contains discrete glycylglycine (HGly-Gly)(+) cations in general positions and oxalate anions which lie across centres of inversion. Although the geometry of the (HGly-Gly)(+) cation is not significantly different compared with other structures containing this residue, a few changes in conformation are observed which indicate the presence of molecular interactions. The molecular network in the crystal consists of one nearly linear O-H...O, five N-H...O and two weak C-H.O hydrogen bonds.
