The crystal structure described by RbAlCl4 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 10-coordinate geometry to one Cl(1), three equivalent Cl(2), 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 bent 150 degrees geometry to one Rb(1) and one Al(1) atom. In the second Cl site, Cl(2) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one Al(1) atom. In the third Cl site, Cl(3) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one Al(1) atom. is represented by the CIF file [CIF]
