The title molecular salt, C(4)H(12)N(2) (2+)·C(10)H(6)O(6)S(2) (2-), consists of a piperazinium cation and a 1,5-naphthalene-disulfonate anion. Crystallographic inversion centers are situated at the center of the ring of the dication as well as at the midpoint of the central carbon-carbon bond in the dianion. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the cations and anions.
标题分子盐C(4)H(12)N(2)(2+)·C(10)H(6)O(6)S(2)(2-)由一个哌嗪鎓阳离子和一个1,5-萘二磺酸盐阴离子组成。晶体学倒转中心位于二价阳离子环的中心以及二价阴离子中心碳-碳键的中点。在晶体中,分子间的N-H⋯O氢键将阳离子和阴离子连接起来。
