The material structure described by Ag2HgO2 crystallizes in the tetragonal P4_32_12 space group. Ag(1) is bonded in a linear geometry to two equivalent O(1) atoms. Hg(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. O(1) is bonded to two equivalent Ag(1) and two equivalent Hg(1) atoms to form corner-sharing OAg2Hg2 tetrahedra. is represented by the CIF card [CIF]
