A new transition metal complex directedmercury thioantimonate, [dienH2]Hg2Sb2S6（dien = diethylenetriamine）, has been synthesized by solvothermal reaction of HgCl2, Sb and S in diethylenetriamine solution at 400 K. The crystal structure was characterized by elemental analysis and single-crystal X-ray diffraction. The title compound crystallizes in the orthorhombic system （Cmca）. The structure consists of two-dimensional （2D） [Hg2Sb2S6]2 -layer and protonated diethylenetriamine cation[dienH2]2＋. These two types of units are interlinked via various hydrogen-bonding interactions to from a two-dimensional （3D） framework.
