Abstract: The barium cation in the centrosymmetric title compound, [Ba₂(C₅H₂N₃O₅)₄(H₂O)₈], is in a ten-coordinate environment with two anionic ligands and four water molecules. The Ba-O bond distances lie in the range 2.723 (2)-3.260 (2) Å. The deprotonated O atom of the ligand bridges the Ba atoms to form a dimeric unit, forming an approximately regular parallelogram Ba₂O₂ motif. The dimeric units are linked in a three-dimensional network by hydrogen bonds.
