The title compound, C(6)H(18)N(2) (2+)·2C(6)H(4)NO(2) (-), consists of a doubly protonated hexa-methyl-enediammonium dication and two pyridine-2-carboxyl-ate anions. These ions inter-act by means of inter-molecular N-H⋯O and N-H⋯N hydrogen bonds to form a two-dimensional array. The carboxyl-ate groups of the anions appear to be delocalized on the basis of the C-O bond lengths.
标题化合物C(6)H(18)N(2) (2+)·2C(6)H(4)NO(2) (-)由一个双质子化的六亚甲基二铵双阳离子和两个吡啶-2-羧酸盐阴离子组成。这些离子通过分子间的N-H⋯O和N-H⋯N氢键相互作用,形成二维阵列。基于C-O键长,阴离子的羧酸盐基团似乎是离域的。
