The Hg(II) ion in the title centrosymmetric dinuclear complex, [Hg(2)Cl(4)(C(13)H(12)N(2))(2)]·[HgCl(2)], adopts a distorted square-pyramidal geometry, being coordinated by the bis-chelating N-heterocyclic ligand, two bridging Cl atoms and one terminal Cl atom. One of the bridging Hg-Cl bonds [2.8428 (11) Å] is significantly longer than the other [2.5327 (10) Å]. In the crystal, there are weak π-π inter-actions [centroid-centroid distance = 3.630 (3) Å] between the aromatic rings of the discrete units. The HgCl(2) adduct molecule is located on an inversion centre and has an Hg-Cl bond length of 2.2875 (11) Å.
在标题中的中心对称双核配合物[Hg₂Cl₄(C₁₃H₁₂N₂)₂]·[HgCl₂]中，Hg(II)离子采用扭曲的四方锥几何构型，由双螯合的N-杂环配体、两个桥连Cl原子和一个端基Cl原子配位。其中一个桥连的Hg-Cl键[2.8428 (11) Å]明显长于另一个[2.5327 (10) Å]。在晶体中，离散单元的芳香环之间存在弱的π-π相互作用[质心-质心距离 = 3.630 (3) Å]。HgCl₂加合物分子位于一个对称中心上，Hg-Cl键长为2.2875 (11) Å。
