The structure described by Rb2Hg3Te4 crystallizes in the orthorhombic Pbcn space group. Rb(1) is bonded in a 9-coordinate geometry to one Hg(1), one Hg(2), three equivalent Te(2), and four equivalent Te(1) atoms. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Te(1), and two equivalent Te(2) atoms. In the second Hg site, Hg(2) is bonded in a 4-coordinate geometry to one Rb(1), one Te(1), and two equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to four equivalent Rb(1), one Hg(1), and one Hg(2) atom. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to three equivalent Rb(1), one Hg(1), and two equivalent Hg(2) atoms. is represented by the CIF file [CIF]
