The compound described by MgHg4(WO4)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Hg(3), one O(1), and one O(3) atom. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(2), one O(5), one O(6), one O(7), and one O(8) atom to form edge-sharing WO6 octahedra. In the second W site, W(2) is bonded to one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom to form distorted edge-sharing WO6 octahedra. There are four inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a single-bond geometry to one O(5) atom. In the second Hg site, Hg(2) is bonded in a distorted L-shaped geometry to one O(2) and one O(4) atom. In the third Hg site, Hg(3) is bonded in a 2-coordinate geometry to two equivalent Mg(1) atoms. In the fourth Hg site, Hg(4) is bonded in a distorted single-bond geometry to one O(7) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Mg(1) and one W(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one W(1) and one Hg(2) atom. In the third O site, O(3) is bonded in a linear geometry to one Mg(1) and one W(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one W(2) and one Hg(2) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one W(1), one W(2), and one Hg(1) atom. In the sixth O site, O(6) is bonded in a water-like geometry to one W(1) and one W(2) atom. In the seventh O site, O(7) is bonded in a trigonal planar geometry to one W(1), one W(2), and one Hg(4) atom. In the eighth O site, O(8) is bonded in a bent 120 degrees geometry to one W(1) and one W(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
