Abstract: In the crystal structure of {[Ag(BrO₃)(C₁₀H₈N₂)]·2.5H₂O}_n, the Ag atom is coordinated by the N atoms of two different spacer donor ligands [Ag-N = 2.147  (2) and 2.152  (2)  Å, and N-Ag-N = 172.0  (1)°], but is connected only weakly to the O atoms of two different bromate counter-ions [Ag-O = 2.877  (3) and 2.972  (3)  Å, and O-Ag-O = 162.3  (1)°]; the coordination geometry of the Ag atom is approximately planar. The (C₁₀H₈N₂)Ag chains, which propagate along [10], are cross-linked in the b direction by bromate anions and AgAg [3.3197  (6)  Å] interactions, thus forming sheets.
