Cd Fe Cl Cl
FeCdCl2 crystallizes in the monoclinic Cm space group. Fe(1) is bonded in a 6-coordinate geometry to two equivalent Cd(1) and four equivalent Cl(1) atoms. There is one shorter (2.27 Å) and one longer (2.58 Å) Fe(1)-Cd(1) bond length. There are two shorter (2.51 Å) and two longer (2.82 Å) Fe(1)-Cl(1) bond lengths. Cd(1) is bonded in a distorted water-like geometry to two equivalent Fe(1) and two equivalent Cl(1) atoms. Both Cd(1)-Cl(1) bond lengths are 1.69 Å. Cl(1) is bonded in a distorted single-bond geometry to two equivalent Fe(1) and one Cd(1) atom.
