Crystals of brucinium 3,5-dinitro­benzoate methanol solvate, C₂₃H₂₇N₂O₄⁺·C₇H₃N₂O₆^-·CH₃OH, (I), brucinium 3,5-dinitro­benzoate methanol disolvate, C₂₃H₂₇N₂O₄⁺·C₇H₃N₂O₆^-·2CH₃OH, (II), and brucinium 3,5-dinitro­benzoate trihydrate, C₂₃H₂₇N₂O₄⁺·C₇H₃N₂O₆^-·3H₂O, (III), were obtained from methanol [for (I) and (II)] or ethanol solutions [for (III)]. The brucinium cations and 3,5-dinitro­benzoate anions are linked by ionic N-H⁺O^- hydrogen bonds. In the crystals of (I), (II) and (III), the brucinium cations exhibit different modes of packing, viz. corrugated ribbons, pillars and corrugated monolayer sheets, respectively. While in (III), the amide O atom of the brucinium cation participates in O-HO hydrogen bonds, in which water mol­ecules are the donors, in (I) and (II), the amide O atom of the brucinium cation is involved in weak C-HO hydrogen bonds and other brucinium cations are the donors.
