Abstract: The title compound, C₁₅H₁₁N₃O₃·2H₂O, crystallizes with terpyridine dioxide molecules positioned on mirror planes in the space group Pnma. Catemeric assemblages of terpyridine molecules [C-H^-O-⁺N = 3.386  (4)  Å] are linked by bridging water molecules [C-HO = 3.288  (4) and 3.386  (4)  Å; O-H^-O-⁺N = 2.837  (3) and 2.878  (4)  Å], giving stacks of two-dimensional undulating motifs.
