Crystal structure of bis(2-aminoanilinium) hydrogen phosphate

Abstract

In the title compound, the hydrogen phosphate anions are linked by O—H⋯O hydrogen bonds into chains parallel to [100]. The inorganic anionic chains and the organic cations are linked by N—H⋯O and N—H⋯N hydrogen bonds, forming a two-dimensional supra­molecular network extending parallel to (001).

“…Acids such as sulfuric, nitric, oxalic, phosphoric, substituted sulfonic, etc. when mixed in water with amines give acidic or neutral salts that may be soluble in organic solvents: this solubility allows for the study of their interactions with metal halides, acetates, nitrates, perchlorates, etc, which yield new adducts and complexes in which the conjugate anion of the acid behaves as a ligand, usually coordinating the metal ion (Najafi et al, 2011a,b;Ittyachan et al, 2016;Majeed & Wendt, 2016).…”
