The structure described by Ba2DyCu2HgO7 crystallizes in the tetragonal P4/mmm space group. Ba(1) is bonded in a 9-coordinate geometry to one O(3), four equivalent O(1), and four equivalent O(2) atoms. Dy(1) is bonded in a body-centered cubic geometry to eight equivalent O(2) atoms. Cu(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. Hg(1) is bonded in a linear geometry to two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to four equivalent Ba(1) and one Hg(1) atom. In the second O site, O(2) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Dy(1), and two equivalent Cu(1) atoms. In the third O site, O(3) is bonded in a distorted linear geometry to two equivalent Ba(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
