The material structure described by EuHg3 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded to four equivalent Hg(2) and eight equivalent Hg(1) atoms to form a mixture of corner and face-sharing EuHg12 cuboctahedra. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 4-coordinate geometry to four equivalent Eu(1) atoms. In the second Hg site, Hg(2) is bonded in a 4-coordinate geometry to four equivalent Eu(1) atoms. is represented by the CIF file [CIF]
