Abstract	In the crystal structure of the nitrate salt, columns of di-cationic macrocycles, each disposed about a center of inversion, are interspersed by pairs of nitrate anions that form charged-assisted N–H···O hydrogen-bonding interactions, reinforced by C–H···O contacts. The topology of the resulting supramolecular architecture is that of a linear chain and these associate via further weak C–H···O contacts. In the structure of the acetate trihydrate, di-cationic macrocycles are circumscribed by 32-membered rings defined by O–H···O interactions, involving the acetate anions and solvent water molecules. Systematic variations in the geometric parameters in the molecular structures are correlated with the influence of intermolecular interactions. The nitrate crystallizes in the monoclinic space group P2$_{1}$/n with a = 8.3524(11) Å, b = 12.5497(16) Å, c = 11.1208(16) Å, β = 103.180(3)°, and Z = 2. The acetate trihydrate also crystallizes in the monoclinic space group P2$_{1}$/n with a = 9.6679(15) Å, b = 15.278(2) Å, c = 9.8376(18) Å, β = 106.068(5)°, and Z = 2.
