The molecule of 3,5-bis{4-[(benzimidazol-1-yl)methyl]phenyl}-4H-1,2,4-triazol-4-amine (L), C(30)H(24)N(8), has an antiperiplanar conformation of the two terminal benzimidazole groups and forms two-dimensional networks along the crystallographic b axis via two types of intermolecular hydrogen bonds. However, in catena-poly[[[dichloridomercury(II)]-μ-3,5-bis{4-[(benzimidazol-1-yl)methyl]phenyl}-4H-1,2,4-triazol-4-amine] dichloromethane hemisolvate], {[HgCl(2)(C(30)H(24)N(8))]·0.5CH(2)Cl(2)}(n), synthesized by the combination of L with HgCl(2), the L ligand adopts a synperiplanar conformation. The Hg(II) cation lies in a distorted tetrahedral environment, which is defined by two N atoms and two Cl atoms to form a one-dimensional zigzag chain. These zigzag chains stack via hydrogen bonds which expand the dimensionality of the structure from one to two.
3,5-双{4-[(苯并咪唑-1-基)甲基]苯基}-4H-1,2,4-三唑-4-胺（L），化学式为C(30)H(24)N(8)，其两个末端苯并咪唑基团呈反叠构象，并通过两种分子间氢键沿结晶学b轴形成二维网络。然而，在通过L与HgCl(2)合成的链状聚[[[二氯汞(II)]-μ-3,5-双{4-[(苯并咪唑-1-基)甲基]苯基}-4H-1,2,4-三唑-4-胺]二氯甲烷半溶剂合物]，即{[HgCl(2)(C(30)H(24)N(8))]·0.5CH(2)Cl(2)}(n)中，L配体采取顺叠构象。Hg(II)阳离子处于扭曲的四面体环境中，由两个N原子和两个Cl原子确定，形成一维锯齿链。这些锯齿链通过氢键堆积，将结构的维度从一维扩展到二维。
