Abstract: In the title compound, 2C₃H₈NO₃⁺·.C₂O₄^2-·2H₂O, the serine molecule exists in the cationic form with an uncharged carboxylic acid group and a positively charged amino group. The oxalic acid molecule exists as a double negatively charged oxalate anion. Two independent oxalate anions lie across inversion centres. The aggregation of individual molecules differs distinctly from other similar complexes.
