The structure described by AcHg3 crystallizes in the hexagonal P6_3/mmc space group. Ac(1) is bonded to twelve equivalent Hg(1) atoms to form a mixture of distorted face and corner-sharing AcHg12 cuboctahedra. Hg(1) is bonded in a 10-coordinate geometry to four equivalent Ac(1) and six equivalent Hg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
