The new ligand 1,1′-bis(pyridin-4-ylmethyl)-2,2′-bi-1H-benzimidazole has been combined with HgX2 (X = Cl, Br and I) to create three one-dimensional coordination polymers. The three complexes have one-dimensional zigzag chains and the HgII centres are in a distorted tetrahedral [HgX2N2] geometry in each case.
