The crystal structure described by Hg(TeO3)2 crystallizes in the monoclinic P2_1/c space group. Hg(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(5) atom to form distorted HgO5 trigonal bipyramids that share corners with four equivalent Te(2)O5 square pyramids, corners with two equivalent Te(1)O5 trigonal bipyramids, and  an edgeedge with one Te(1)O5 trigonal bipyramid. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(6) atom to form TeO5 trigonal bipyramids that share corners with two equivalent Te(2)O5 square pyramids, corners with two equivalent Hg(1)O5 trigonal bipyramids,  an edgeedge with one Te(2)O5 square pyramid, and  an edgeedge with one Hg(1)O5 trigonal bipyramid. In the second Te site, Te(2) is bonded to one O(1), one O(3), one O(4), one O(5), and one O(6) atom to form distorted TeO5 square pyramids that share corners with two equivalent Te(1)O5 trigonal bipyramids, corners with four equivalent Hg(1)O5 trigonal bipyramids, and  an edgeedge with one Te(1)O5 trigonal bipyramid. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Hg(1), one Te(1), and one Te(2) atom. In the second O site, O(2) is bonded in a water-like geometry to one Hg(1) and one Te(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Hg(1), one Te(1), and one Te(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Hg(1), one Te(1), and one Te(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Hg(1) and one Te(2) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one Te(1) and one Te(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
