Abstract: In the title complex, (C₁₀H₉N₂)[Pr(C₆H₂N₂O₄)₂(H₂O)₅], the Pr atom is nine-coordinated by nine O atoms from two pyridazine-4,5-dicarboxylate anions and five water molecules. It is noteworthy that there is a protonated bipyridine molecule in the structure. Intermolecular O-HO, O-HN and N-HN hydrogen bonds are present, resulting in a three-dimensional network.
