DyHg2 crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of one DyHg2 sheet oriented in the (0, 0, 1) direction. Dy is bonded in a distorted hexagonal planar geometry to six equivalent Hg atoms. All Dy–Hg bond lengths are 3.10 Å. Hg is bonded in a distorted trigonal planar geometry to three equivalent Dy atoms.
DyHg2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Dy is bonded to twelve equivalent Hg atoms to form a mixture of distorted edge and face-sharing DyHg12 cuboctahedra. All Dy–Hg bond lengths are 3.34 Å. Hg is bonded in a 9-coordinate geometry to six equivalent Dy and three equivalent Hg atoms. All Hg–Hg bond lengths are 2.86 Å.
