The material structure described by MgHg2(MoO4)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded in a distorted see-saw-like geometry to one O(1), one O(2), one O(3), and one O(5) atom. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(5), one O(6), one O(7), and one O(8) atom. In the second Mo site, Mo(2) is bonded in an octahedral geometry to one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 3-coordinate geometry to one O(3), one O(6), and one O(8) atom. In the second Hg site, Hg(2) is bonded in a distorted T-shaped geometry to one O(1), one O(4), and one O(5) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mg(1), one Mo(1), and one Hg(2) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Mg(1) and one Mo(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Mg(1), one Mo(2), and one Hg(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Mo(2) and one Hg(2) atom. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to one Mg(1), one Mo(1), one Mo(2), and one Hg(2) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to one Mo(1), one Mo(2), and one Hg(1) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one Mo(1) and one Mo(2) atom. In the eighth O site, O(8) is bonded in a distorted trigonal planar geometry to one Mo(1), one Mo(2), and one Hg(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
