The compound described by Hg3Se2Cl2 crystallizes in the cubic I2_13 space group. Hg(1) is bonded in a see-saw-like geometry to two equivalent Se(1) and two equivalent Cl(1) atoms. Se(1) is bonded in a distorted T-shaped geometry to three equivalent Hg(1) atoms. Cl(1) is bonded in a trigonal planar geometry to three equivalent Hg(1) atoms. is represented by the CIF file [CIF]
