Pt5HgP crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 11-coordinate geometry to two equivalent Pt(2), five equivalent Pt(1), two equivalent Hg(1), and two equivalent P(1) atoms. In the second Pt site, Pt(2) is bonded in a distorted square co-planar geometry to eight equivalent Pt(1) and four equivalent Hg(1) atoms. Hg(1) is bonded to four equivalent Pt(2) and eight equivalent Pt(1) atoms to form a mixture of face and corner-sharing HgPt12 cuboctahedra. P(1) is bonded in a body-centered cubic geometry to eight equivalent Pt(1) atoms.

In the first Pt site, Pt(1) is bonded in a 11-coordinate geometry to two equivalent Pt(2), five equivalent Pt(1), two equivalent Hg(1), and two equivalent P(1) atoms. Both Pt(1)-Pt(2) bond lengths are 2.94 Å. There are four shorter (2.79 Å) and one longer (2.84 Å) Pt(1)-Pt(1) bond length. Both Pt(1)-Hg(1) bond lengths are 2.94 Å. Both Pt(1)-P(1) bond lengths are 2.43 Å. In the second Pt site, Pt(2) is bonded in a distorted square co-planar geometry to eight equivalent Pt(1) and four equivalent Hg(1) atoms. All Pt(2)-Hg(1) bond lengths are 2.79 Å. Hg(1) is bonded to four equivalent Pt(2) and eight equivalent Pt(1) atoms to form a mixture of face and corner-sharing HgPt12 cuboctahedra. P(1) is bonded in a body-centered cubic geometry to eight equivalent Pt(1) atoms.
