In the title coordination polymer, Hg₄Cl₄(C₂₆H₂₀N₆), one Hg(II) ion is coordinated by four N atoms from the benzylbis((pyridin-2-yl)methyl-idenehydrazone) ligand and two Cl⁻ ions in a very distorted cis-HgCl₂N₄ octa-hedral geometry. The other Hg(II) ion is coordinated in a distorted tetra-hedral geometry by four Cl⁻ ions. Bridging chloride ions link the Hg(II) ions into a chain propagating in [010]: the Hg-Cl bridging bonds are significantly longer than the terminal bonds. The dihedral angle between the central benzene rings of the ligand is 83.3 (2)°. The packing is consolidated by weak C-H⋯Cl hydrogen bonds and C-H⋯π inter-actions.
在标题配位聚合物[Hg₄Cl₄(C₂₆H₂₀N₆)]ₙ中，一个Hg(II)离子由来自苄基双((吡啶-2-基)亚甲基腙)配体的四个N原子和两个Cl⁻离子配位，形成非常扭曲的顺式-HgCl₂N₄八面体几何构型。另一个Hg(II)离子由四个Cl⁻离子以扭曲的四面体几何构型配位。桥连氯离子将Hg(II)离子连接成在[010]方向延伸的链：Hg-Cl桥连键明显长于端基键。配体中心苯环之间的二面角为83.3 (2)°。堆积通过弱的C-H⋯Cl氢键和C-H⋯π相互作用得以巩固。
