The crystal structure described by Pd2Hg5 crystallizes in the tetragonal P4/mbm space group. Pd(1) is bonded to two equivalent Pd(1), two equivalent Hg(2), and eight equivalent Hg(1) atoms to form a mixture of distorted face, corner, and edge-sharing PdHg10Pd2 cuboctahedra. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 10-coordinate geometry to four equivalent Pd(1), one Hg(2), and five equivalent Hg(1) atoms. In the second Hg site, Hg(2) is bonded in a distorted q6 geometry to four equivalent Pd(1), two equivalent Hg(2), and four equivalent Hg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
