Sažetak
4-Amino-trans-azobenzene {; ; or 4-[(E)-phenyldiazenyl]aniline}; ; can form isomeric salts depending on the site of protonation. Both orange bis{; ; 4-[(E)-phenyldiazenyl]anilinium}; ; hydrogen phosphate, 2C12H12N3+· HPO42− , and purple 4-[(E)-phenyldiazenyl]anilinium dihydrogen phosphate phosphoric acid solvate, C12H12N3+· H2PO4− · H3PO4, (II), have layered structures formed through O— HO and N— HO hydrogen bonds. Additionally, azobenzene fragments in (I) are assembled through C— H...π interactions and in (II) through π – π interactions. Arguments for the colour difference are tentatively proposed.
