摘要：

The crystal structures of two salts of chloranilic acid (2,5-dichloro-3,6-dihydroxy-p-benzoquinone), namely pyridinium chloranilate monohydrate, C5H6N+. C6HCl2O4-. H2O, (I), and bis(1,2-diazinium) chloranilate, 2C(4)H(5)N(2)(+). C6Cl2O42-, (II), have been determined at room temperature. In (I) and (II), the cations and 2.582 (3) A in (II). The H atom in the hydrogen bond in (I) was located at the N-atom site [N-H = 1.09(5) and H ... O = 1.70(5) Angstrom], while that in (II) was found near the center of N ... O [N ... H = 1.32(5) and H ... O = 1.28 (5) Angstrom].
