Abstract: The crystal structure of the title compound, C₆H₈N₄S₂²⁺·2C₆H₇N₄S₂⁺·4C₇H₄NO₄^-, comprises diprotonated diaminobithiazole (DABT) dications located on inversion centers, monoprotonated DABT cations and nitrobenzoate anions. The relatively short C-N(amino) bond distances, ranging from 1.310 (2) to 1.350 (2) Å, indicate electron delocalization between the amino groups and thiazole rings. Intermolecular N-HO and N-HN hydrogen bonds stabilize the crystal packing.
