SmCl2 crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 6-coordinate geometry to three equivalent Cl(1) and three equivalent Cl(2) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in a distorted trigonal planar geometry to three equivalent Sm(1) atoms. In the second Cl site, Cl(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sm(1) atoms.
SmCl2 crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 6-coordinate geometry to three equivalent Cl(1) and three equivalent Cl(2) atoms. There is one shorter (2.84 Å) and two longer (2.89 Å) Sm(1)-Cl(1) bond lengths. There is one shorter (2.82 Å) and two longer (2.85 Å) Sm(1)-Cl(2) bond lengths. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in a distorted trigonal planar geometry to three equivalent Sm(1) atoms. In the second Cl site, Cl(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sm(1) atoms.
