Structures of four organic acid-base adducts from 4-aminoantipyrine, 3,5-dinitrobenzoic acid, anthranilic acid, 5-nitrosalicylic acid, and 1, 5-naphthalenedisulfonic acid

•Four superamolecular adducts have been prepared and characterized. Classical H-bonds are the primary forces in the four adducts.•The other non-covalent interactions are discussed in detail.•Discrete ions can be constructed into 2D-3D structures via non-covalent forces.
