The material structure described by GdHg3 crystallizes in the hexagonal P6_3/mmc space group. Gd(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of corner and face-sharing GdHg12 cuboctahedra. Hg(1) is bonded in a 4-coordinate geometry to four equivalent Gd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
