PdF2 is Hydrophilite structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Pd2+ is bonded to six equivalent F1- atoms to form a mixture of corner and edge-sharing PdF6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are two shorter (2.13 Å) and four longer (2.22 Å) Pd–F bond lengths. F1- is bonded in a trigonal planar geometry to three equivalent Pd2+ atoms.
PdF3 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Pd is bonded to six equivalent F atoms to form corner-sharing PdF6 octahedra. The corner-sharing octahedral tilt angles are 42°. All Pd–F bond lengths are 2.05 Å. F is bonded in a bent 150 degrees geometry to two equivalent Pd atoms.
PdF4 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. Pd4+ is bonded to six F1- atoms to form corner-sharing PdF6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Pd–F bond distances ranging from 1.88–2.06 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Pd4+ atom. In the second F1- site, F1- is bonded in a bent 120 degrees geometry to two equivalent Pd4+ atoms.
PdF2 crystallizes in the cubic Pa-3 space group. The structure is three-dimensional. Pd2+ is bonded to six equivalent F1- atoms to form corner-sharing PdF6 octahedra. The corner-sharing octahedral tilt angles are 60°. All Pd–F bond lengths are 2.19 Å. F1- is bonded in a trigonal planar geometry to three equivalent Pd2+ atoms.
