PmCl2 is trigonal omega-like structured and crystallizes in the tetragonal P4_2/mnm space group. Pm(1) is bonded to six equivalent Cl(1) atoms to form a mixture of corner and edge-sharing PmCl6 octahedra. The corner-sharing octahedral tilt angles are 38°. Cl(1) is bonded in a 3-coordinate geometry to three equivalent Pm(1) atoms.

Pm(1) is bonded to six equivalent Cl(1) atoms to form a mixture of corner and edge-sharing PmCl6 octahedra. The corner-sharing octahedral tilt angles are 38°. There are two shorter (2.79 Å) and four longer (2.83 Å) Pm(1)-Cl(1) bond lengths. Cl(1) is bonded in a 3-coordinate geometry to three equivalent Pm(1) atoms.
