Hf Cd Cl Cl
HfCdCl2 crystallizes in the monoclinic Cm space group. Hf(1) is bonded in a 6-coordinate geometry to six equivalent Cl(1) atoms. There are a spread of Hf(1)-Cl(1) bond distances ranging from 2.57-3.14 Å. Cd(1) is bonded in a 4-coordinate geometry to four equivalent Cl(1) atoms. There are two shorter (2.57 Å) and two longer (3.03 Å) Cd(1)-Cl(1) bond lengths. Cl(1) is bonded in a 2-coordinate geometry to three equivalent Hf(1) and two equivalent Cd(1) atoms.
