Abstract: 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)O hydrogen bonds, in which water molecules are the donors, in (I)O hydrogen bonds and other brucinium cations are the donors.
Formula: C23H27N2O4+·C7H3N2O6-·CH4O, C23H27N2O4+·C7H3N2O6-·2CH4O and C23H27N2O4+·C7H3N2O6-·3H2O
