The compound described by Sr(AlCl4)2 crystallizes in the tetragonal I4_1/acd space group. The structure consists of a Sr(AlCl4)2 framework. Sr(1) is bonded to four equivalent Cl(1) and four equivalent Cl(2) atoms to form distorted SrCl8 hexagonal bipyramids that share edges with four equivalent Al(1)Cl4 tetrahedra. Al(1) is bonded to two equivalent Cl(1) and two equivalent Cl(2) atoms to form AlCl4 tetrahedra that share edges with two equivalent Sr(1)Cl8 hexagonal bipyramids. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in an L-shaped geometry to one Sr(1) and one Al(1) atom. In the second Cl site, Cl(1) is bonded in a distorted L-shaped geometry to one Sr(1) and one Al(1) atom. is represented by the CIF card [CIF]
