RbCaCl3 is Orthorhombic Perovskite-like structured and crystallizes in the trigonal R3c space group. Rb(1) is bonded in a 9-coordinate geometry to nine equivalent Cl(1) atoms. Ca(1) is bonded to six equivalent Cl(1) atoms to form corner-sharing CaCl6 octahedra. The corner-sharing octahedral tilt angles are 19°. Cl(1) is bonded in a 5-coordinate geometry to three equivalent Rb(1) and two equivalent Ca(1) atoms.
