PdHgF4 crystallizes in the monoclinic P2_1/c space group. Pd(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form PdF6 octahedra that share corners with four equivalent Pd(1)F6 octahedra and corners with eight equivalent Hg(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 56-63°. Hg(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form HgF6 octahedra that share corners with four equivalent Hg(1)F6 octahedra and corners with eight equivalent Pd(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 57-64°. There are two inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to two equivalent Pd(1) and one Hg(1) atom. In the second F site, F(2) is bonded in a trigonal planar geometry to one Pd(1) and two equivalent Hg(1) atoms.

The corner-sharing octahedral tilt angles range from 56-63°. Both Pd(1)-F(2) bond lengths are 2.20 Å. There are two shorter (2.23 Å) and two longer (2.24 Å) Pd(1)-F(1) bond lengths. Hg(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form HgF6 octahedra that share corners with four equivalent Hg(1)F6 octahedra and corners with eight equivalent Pd(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 57-64°. Both Hg(1)-F(1) bond lengths are 2.39 Å. There are two shorter (2.31 Å) and two longer (2.35 Å) Hg(1)-F(2) bond lengths. There are two inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to two equivalent Pd(1) and one Hg(1) atom. In the second F site, F(2) is bonded in a trigonal planar geometry to one Pd(1) and two equivalent Hg(1) atoms.
