The title complex [(C8H9NO2)·HgI2]n has been synthesized from the reaction of pyridine-3-ethylformate with mercury iodide in the mixture of DMF and absolute methanol. Its structure was determined by IR, elemental analysis and X-ray single-crystal diffraction analysis. The crystal is of monoclinic system, space group P21/n with a = 4.3397(5), b = 25.051(3), c = 12.3719(13) , β = 92.2130(10)o, C8H9HgI2NO2, Mr = 605.55, V = 1344.0(3) 3, Z = 4, Dc = 2.993 mg·m-3, F(000) = 1064, μ = 16.024 mm-1, the final R = 0.0258 and wR = 0.0504. In the title complex, the center Hg(Ⅱ ) exhibits a four-coordinated distorted tetrahedral geometry. A three-dimensional network arrangement is presented via Hg…I weak interactions among adjacent molecules.
