Materials Data on CdCl2 by Materials Project
CdCl2 is trigonal omega-like structured and crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three CdCl2 sheets oriented in the (0, 0, 1) direction. Cd2+ is bonded to six equivalent Cl1- atoms to form edge-sharing CdCl6 octahedra. All Cd–Cl bond lengths are 2.68 Å. Cl1- is bonded in a distorted T-shaped geometry to three equivalent Cd2+ atoms.
