Two-dimensional hydrogen-bonded arrays in p-phenylazoanilinium oxalate

A. H. Mahmoudkhani and V. Langer

Abstract: In the title compound, 2C₆H₅N=NC₆H₄NH₃⁺·C₂O₄^2- or 2C₁₂H₁₂N₃⁺·C₂O₄^2-, p-phenylazoaniline is protonated at the amine site to form an organic ammonium cation, and oxalic acid is deprotonated forming an oxalate dianion. The latter occupies a special position at the inversion centre. The structure exhibits a layered hydrogen-bonded framework built up by N-HO hydrogen bonds.
