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).
在两种氯冉酸（2,5 - 二氯 - 3,6 - 二羟基 - 对苯醌）的标题盐晶体中，即氯冉酸乙铵盐，C(2)H(8)N(+)·C(6)HCl(2)O(4)(-)，(I)，以及氯冉酸二乙铵盐，C(4)H(12)N(+)·C(6)HCl(2)O(4)(-)，(II)，氯冉酸根离子以具有对称中心的氢键二聚体形式存在。乙铵离子和二乙铵离子通过N - H…O氢键连接二聚体，在(I)中形成三维氢键网络，在(II)中形成一维链。
