Rb2Hg3(GeS4)2 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 7-coordinate geometry to one S(2), two equivalent S(1), two equivalent S(3), and two equivalent S(4) atoms. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded to one S(1), one S(4), and two equivalent S(2) atoms to form distorted HgS4 trigonal pyramids that share corners with four equivalent Ge(1)S4 tetrahedra and corners with two equivalent Hg(1)S4 trigonal pyramids. In the second Hg site, Hg(2) is bonded in a linear geometry to two equivalent S(3) atoms. Ge(1) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form GeS4 tetrahedra that share corners with four equivalent Hg(1)S4 trigonal pyramids. There are four inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one Hg(1), and one Ge(1) atom. In the second S site, S(2) is bonded in a 4-coordinate geometry to one Rb(1), two equivalent Hg(1), and one Ge(1) atom. In the third S site, S(3) is bonded to two equivalent Rb(1), one Hg(2), and one Ge(1) atom to form distorted corner-sharing SRb2HgGe trigonal pyramids. In the fourth S site, S(4) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one Hg(1), and one Ge(1) atom.
