The crystal structure described by BaAg2(HgO2)2 crystallizes in the tetragonal P4/nbm space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted body-centered cubic geometry to eight equivalent O(1) atoms. In the second Ba site, Ba(1) is bonded in a distorted body-centered cubic geometry to eight equivalent O(1) atoms. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to two equivalent O(1) atoms. In the second Ag site, Ag(1) is bonded in a linear geometry to two equivalent O(1) atoms. In the third Ag site, Ag(1) is bonded in a linear geometry to two equivalent O(1) atoms. There are four inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a linear geometry to two equivalent O(1) atoms. In the second Hg site, Hg(1) is bonded in a linear geometry to two equivalent O(1) atoms. In the third Hg site, Hg(1) is bonded in a linear geometry to two equivalent O(1) atoms. In the fourth Hg site, Hg(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to two Ba(1,1); one Ag(1); and one Hg(1) atom to form a mixture of distorted corner and edge-sharing OBa2AgHg trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
