The compound described by SmHg2 crystallizes in the hexagonal P6/mmm space group. Sm(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of distorted face and edge-sharing SmHg12 cuboctahedra. Hg(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Hg(1) atoms. is represented by the CIF card [CIF]
