Materials Data on AlCdCl4 by Materials Project
CdAlCl4 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of two CdAlCl4 sheets oriented in the (0, 0, 1) direction. Cd is bonded in a distorted rectangular see-saw-like geometry to three Cl atoms. There are two shorter (2.76 Å) and one longer (2.79 Å) Cd–Cl bond lengths. Al is bonded in a tetrahedral geometry to four Cl atoms. There are one shorter (2.11 Å) and three longer (2.18 Å) Al–Cl bond lengths. There are four inequivalent Cl sites. In the first Cl site, Cl is bonded in a water-like geometry to one Cd and one Al atom. In the second Cl site, Cl is bonded in a water-like geometry to one Cd and one Al atom. In the third Cl site, Cl is bonded in a single-bond geometry to one Al atom. In the fourth Cl site, Cl is bonded in a water-like geometry to one Cd and one Al atom.
