RbSrCl3 crystallizes in the tetragonal P4/mbm space group. Rb(1) is bonded in a distorted body-centered cubic geometry to four equivalent Cl(1) and four equivalent Cl(2) atoms. Sr(1) is bonded to two equivalent Cl(1) and four equivalent Cl(2) atoms to form corner-sharing SrCl6 octahedra. The corner-sharing octahedral tilt angles range from 0-34°. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted linear geometry to four equivalent Rb(1) and two equivalent Sr(1) atoms. In the second Cl site, Cl(2) is bonded to two equivalent Rb(1) and two equivalent Sr(1) atoms to form a mixture of distorted edge and corner-sharing ClRb2Sr2 tetrahedra.
