3,5-Bis{4-[(benzimidazol-1-yl)methyl]phenyl}-4H-1,2,4-triazol-4-amine and its one-dimensional polymeric complex with HgCl2.
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.
