在标题化合物C2 H10 N22+·2C 6 H4 NO2 −中，阳离子位于反转中心。不对称单元由一个烟酸根阴离子和一半乙二胺阳离子组成。所有的氨基H原子参与N-H <$O和N-H <$N氢键。这些氢键将离子单元连接成三维网络。此外，吡啶环之间的π-π相互作用[质心-质心距离= 3.6037（7）π]进一步稳定了晶体结构。
In the title compound, C2H10N22+·2C6H4NO2−, the cation lies on an inversion centre. The asymmetric unit is composed of one nicotinate anion and one half ethylenediaminium cation. All the amino H atoms are involved in N—H⋯O and N—H⋯N hydrogen bonds. These hydrogen bonds link the ionic units into a three-dimensional network. In addition, π–π interactions between pyridine rings [centroid–centroid distance = 3.6037 (7) Å] further stabilize the crystal structure.
