| pubmed-article:21582245 | pubmed:abstractText | In the title salt, C(6)H(8)N(4)S(2) (2+)·2C(7)H(4)NO(4) (-), the diprotonated diamino-bithia-zole dication is located on an inversion center. The carboxyl-ate group of the anion is twisted with respect to the benzene ring, with a dihedral angle of 13.6?(4)°. N-H?O hydrogen bonds involving the amino and ammonium groups of the dication and the carboxyl-ate functionality of the anion generate supra-molecular chains in the crystal. | lld:pubmed |
