In the ionic title complex, (C(13)H(11)N(2))(2)[Ni(C(4)N(2)S(2))(2)], the Ni(II) ion is located on an inversion centre so the asymmetric unit contains one-half Ni(mnt)(2) dianion (mnt(2-) is maleonitrile-dithiolate) and one 1-(3-cyano-benz-yl)pyridinium cation (CNBzPy). The Ni(II) ion in the Ni(mnt)(2) anion is coordinated by four S atoms of two mnt(2-) ligands, and exhibits square-planar coordination geometry. In the CNBzPy cation, the benzene and pyridine rings are twisted with respect to the C/C/N plane incorporating the methyl-ene C atom that links them. The crystal structure is stabilized by Coulombic inter-actions.
在离子型标题配合物(C₁₃H₁₁N₂)₂[Ni(C₄N₂S₂)₂]中，Ni(II)离子位于一个对称中心上，因此不对称单元包含半个[Ni(mnt)₂]²⁻二价阴离子（mnt²⁻为马来腈二硫醇盐）和一个1-(3-氰基苄基)吡啶鎓阳离子([CNBzPy]⁺)。[Ni(mnt)₂]²⁻阴离子中的Ni(II)离子由两个mnt²⁻配体的四个S原子配位，呈现出平面正方形配位几何构型。在[CNBzPy]⁺阳离子中，苯环和吡啶环相对于包含连接它们的亚甲基C原子的C/C/N平面发生扭曲。晶体结构通过库仑相互作用得以稳定。
