Ethylammonium and diethylammonium salts of chloranilic acid.
In the crystals of two title salts of chloranilic acid (2,5-dichloro-3,6-dihydroxy-p-benzoquinone), namely ethylammonium chloranilate, C(2)H(8)N(+).C(6)HCl(2)O(4)(-), (I), and diethylammonium chloranilate, C(4)H(12)N(+).C(6)HCl(2)O(4)(-), (II), the chloranilate ions are present as a hydrogen-bonded dimer which has an inversion center. The ethylammonium and diethylammonium ions link the dimers through N-H.O hydrogen bonds, forming a three-dimensional hydrogen-bond network in (I) and a one-dimensional chain in (II).
