CsAlCl4 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 10-coordinate geometry to one Cl(2), three equivalent Cl(1), and six equivalent Cl(3) atoms. Al(1) is bonded in a tetrahedral geometry to one Cl(1), one Cl(2), and two equivalent Cl(3) atoms. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one Al(1) atom. In the second Cl site, Cl(2) is bonded in a distorted single-bond geometry to one Cs(1) and one Al(1) atom. In the third Cl site, Cl(3) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one Al(1) atom.
CsAlCl4 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 10-coordinate geometry to one Cl(2), three equivalent Cl(1), and six equivalent Cl(3) atoms. The Cs(1)-Cl(2) bond length is 3.61 Å. There is one shorter (3.65 Å) and two longer (3.93 Å) Cs(1)-Cl(1) bond lengths. There are a spread of Cs(1)-Cl(3) bond distances ranging from 3.61-3.78 Å. Al(1) is bonded in a tetrahedral geometry to one Cl(1), one Cl(2), and two equivalent Cl(3) atoms. The Al(1)-Cl(1) bond length is 2.14 Å. The Al(1)-Cl(2) bond length is 2.14 Å. Both Al(1)-Cl(3) bond lengths are 2.15 Å. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one Al(1) atom.
