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.

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. Both Pd(1)-Pd(1) bond lengths are 2.98 Å. Both Pd(1)-Hg(2) bond lengths are 2.91 Å. There are four shorter (2.93 Å) and four longer (3.04 Å) Pd(1)-Hg(1) bond lengths. 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. The Hg(1)-Hg(2) bond length is 2.97 Å. There are a spread of Hg(1)-Hg(1) bond distances ranging from 2.96-3.22 Å. 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. Both Hg(2)-Hg(2) bond lengths are 2.98 Å.
