SmCl2 is trigonal omega-like structured and crystallizes in the tetragonal P4_2/mnm space group. Sm(1) is bonded to six equivalent Cl(1) atoms to form a mixture of edge and corner-sharing SmCl6 octahedra. The corner-sharing octahedral tilt angles are 39°. Cl(1) is bonded in a 3-coordinate geometry to three equivalent Sm(1) atoms.

Sm(1) is bonded to six equivalent Cl(1) atoms to form a mixture of edge and corner-sharing SmCl6 octahedra. The corner-sharing octahedral tilt angles are 39°. There are two shorter (2.78 Å) and four longer (2.81 Å) Sm(1)-Cl(1) bond lengths. Cl(1) is bonded in a 3-coordinate geometry to three equivalent Sm(1) atoms.
