The material structure described by UHg(MoO4)4 crystallizes in the monoclinic P2/c space group. U(1) is bonded to one O(2), two equivalent O(1), two equivalent O(6), and two equivalent O(8) atoms to form distorted UO7 pentagonal bipyramids that share corners with two equivalent Hg(1)O7 pentagonal bipyramids. 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(3), one O(4), one O(5), one O(7), and one O(9) atom. In the second Mo site, Mo(2) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(4), one O(5), one O(6), and one O(9) atom. Hg(1) is bonded to one O(3), two equivalent O(5), two equivalent O(7), and two equivalent O(8) atoms to form HgO7 pentagonal bipyramids that share corners with two equivalent U(1)O7 pentagonal bipyramids. There are nine inequivalent O sites. In the first O site, O(7) is bonded in a bent 150 degrees geometry to one Mo(1) and one Hg(1) atom. In the second O site, O(8) is bonded in a linear geometry to one U(1) and one Hg(1) atom. In the third O site, O(9) is bonded in a distorted single-bond geometry to one Mo(1) and one Mo(2) atom. In the fourth O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one U(1), one Mo(1), and one Mo(2) atom. In the fifth O site, O(2) is bonded in a distorted trigonal planar geometry to one U(1) and two equivalent Mo(2) atoms. In the sixth O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Mo(1) and one Hg(1) atom. In the seventh O site, O(4) is bonded in a distorted single-bond geometry to one Mo(1) and one Mo(2) atom. In the eighth O site, O(5) is bonded in a 3-coordinate geometry to one Mo(1), one Mo(2), and one Hg(1) atom.
