Rb2CrCl2I2 is (La,Ba)CuO4-derived structured and crystallizes in the orthorhombic Cmce space group. Rb(1) is bonded in a 9-coordinate geometry to five equivalent I(1) and four equivalent Cl(1) atoms. Cr(1) is bonded to two equivalent I(1) and four equivalent Cl(1) atoms to form corner-sharing CrI2Cl4 octahedra. The corner-sharing octahedra are not tilted. I(1) is bonded to five equivalent Rb(1) and one Cr(1) atom to form distorted IRb5Cr octahedra that share corners with five equivalent I(1)Rb5Cr octahedra, corners with twelve equivalent Cl(1)Rb4Cr2 octahedra, edges with eight equivalent I(1)Rb5Cr octahedra, and faces with four equivalent Cl(1)Rb4Cr2 octahedra. The corner-sharing octahedral tilt angles range from 0-55°. Cl(1) is bonded to four equivalent Rb(1) and two equivalent Cr(1) atoms to form distorted ClRb4Cr2 octahedra that share corners with two equivalent Cl(1)Rb4Cr2 octahedra, corners with twelve equivalent I(1)Rb5Cr octahedra, edges with two equivalent Cl(1)Rb4Cr2 octahedra, faces with four equivalent I(1)Rb5Cr octahedra, and faces with four equivalent Cl(1)Rb4Cr2 octahedra. The corner-sharing octahedral tilt angles range from 0-55°.
Rb2CrCl2I2 is (La,Ba)CuO4-derived structured and crystallizes in the orthorhombic Cmce space group. Rb(1) is bonded in a 9-coordinate geometry to five equivalent I(1) and four equivalent Cl(1) atoms. There are four shorter (3.78 Å) and one longer (3.91 Å) Rb(1)-I(1) bond length. There are two shorter (3.49 Å) and two longer (3.50 Å) Rb(1)-Cl(1) bond lengths. Cr(1) is bonded to two equivalent I(1) and four equivalent Cl(1) atoms to form corner-sharing CrI2Cl4 octahedra. The corner-sharing octahedra are not tilted. Both Cr(1)-I(1) bond lengths are 2.79 Å. There are two shorter (2.42 Å) and two longer (2.87 Å) Cr(1)-Cl(1) bond lengths. I(1) is bonded to five equivalent Rb(1) and one Cr(1) atom to form distorted IRb5Cr octahedra that share corners with five equivalent I(1)Rb5Cr octahedra, corners with twelve equivalent Cl(1)Rb4Cr2 octahedra, edges with eight equivalent I(1)Rb5Cr octahedra, and faces with four equivalent Cl(1)Rb4Cr2 octahedra.
