The title compound, [HgI2(C12H8N4S)], has been synthesized and characterized by single-crystal X-ray diffraction analysis. It crystallizes in monoclinic, space group P21/n with a = 14.086(2), b = 6.0365(6), c = 20.286(2) , β = 108.818(5)°, V = 1632.7(3) 3, Mr = 694.67, Z = 4, Dc = 2.826 g/cm3, μ = 13.331 mm-1, F(000) = 1240, S = 1.108, the final R = 0.0438 and wR = 0.0934 for 3085 observed reflections (I > 2σ(I)). The Hg(II) atom is coordinated by two 2,5-bis(4-pyridyl)-1,3,4-thiadiazole (L) molecules and two iodine anions in a distorted tetrahedral coordination geometry. Mercury atoms are linked by the organic ligands to form a one-dimensional zigzag chain. It is noteworthy that such 1D zigzag chains are extended into a two-dimensional double layer framework through I…I interactions.
