The material described by Yb(AlCl4)2 crystallizes in the tetragonal I4_1/acd space group. The structure consists of a Yb(AlCl4)2 framework. Yb(1) is bonded in a 8-coordinate geometry to four equivalent Cl(1) and four equivalent Cl(2) atoms. Al(1) is bonded in a tetrahedral geometry to two equivalent Cl(1) and two equivalent Cl(2) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted L-shaped geometry to one Yb(1) and one Al(1) atom. In the second Cl site, Cl(2) is bonded in a water-like geometry to one Yb(1) and one Al(1) atom. is represented by the CIF card [CIF]
