The material structure described by RbSr2Cl5 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 9-coordinate geometry to two equivalent Cl(2), two equivalent Cl(3), two equivalent Cl(4), and three equivalent Cl(1) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to two equivalent Cl(2), two equivalent Cl(3), two equivalent Cl(4), and two equivalent Cl(5) atoms. In the second Sr site, Sr(2) is bonded to one Cl(2), one Cl(3), one Cl(4), two equivalent Cl(1), and two equivalent Cl(5) atoms to form distorted edge-sharing SrCl7 pentagonal bipyramids. There are five inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 5-coordinate geometry to three equivalent Rb(1) and two equivalent Sr(2) atoms. In the second Cl site, Cl(2) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one Sr(2), and two equivalent Sr(1) atoms. In the third Cl site, Cl(3) is bonded to two equivalent Rb(1), one Sr(2), and two equivalent Sr(1) atoms to form distorted ClRb2Sr3 trigonal bipyramids that share corners with four equivalent Cl(4)Rb2Sr3 square pyramids, corners with two equivalent Cl(5)Sr4 tetrahedra, corners with four equivalent Cl(3)Rb2Sr3 trigonal bipyramids,  an edgeedge with one Cl(4)Rb2Sr3 square pyramid, edges with two equivalent Cl(5)Sr4 tetrahedra, and  a faceface with one Cl(4)Rb2Sr3 square pyramid. In the fourth Cl site, Cl(4) is bonded to two equivalent Rb(1), one Sr(2), and two equivalent Sr(1) atoms to form distorted ClRb2Sr3 square pyramids that share corners with four equivalent Cl(5)Sr4 tetrahedra, corners with four equivalent Cl(3)Rb2Sr3 trigonal bipyramids, edges with two equivalent Cl(4)Rb2Sr3 square pyramids,  an edgeedge with one Cl(5)Sr4 tetrahedra,  an edgeedge with one Cl(3)Rb2Sr3 trigonal bipyramid, and  a faceface with one Cl(3)Rb2Sr3 trigonal bipyramid. In the fifth Cl site, Cl(5) is bonded to two equivalent Sr(1) and two equivalent Sr(2) atoms to form ClSr4 tetrahedra that share corners with four equivalent Cl(4)Rb2Sr3 square pyramids, corners with two equivalent Cl(5)Sr4 tetrahedra, corners with two equivalent Cl(3)Rb2Sr3 trigonal bipyramids,  an edgeedge with one Cl(4)Rb2Sr3 square pyramid,  an edgeedge with one Cl(5)Sr4 tetrahedra, and edges with two equivalent Cl(3)Rb2Sr3 trigonal bipyramids. is represented by the CIF file [CIF]
