The crystal structure described by RbMnCl3 is (Cubic) Perovskite-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded to six equivalent Cl(1) and six equivalent Cl(2) atoms to form RbCl12 cuboctahedra that share corners with six equivalent Rb(1)Cl12 cuboctahedra, corners with six equivalent Rb(2)Cl12 cuboctahedra, faces with six equivalent Rb(2)Cl12 cuboctahedra, faces with two equivalent Mn(2)Cl6 octahedra, and faces with six equivalent Mn(1)Cl6 octahedra. In the second Rb site, Rb(2) is bonded to three equivalent Cl(2) and nine equivalent Cl(1) atoms to form RbCl12 cuboctahedra that share corners with three equivalent Rb(1)Cl12 cuboctahedra, corners with six equivalent Rb(2)Cl12 cuboctahedra, corners with three equivalent Mn(1)Cl6 octahedra, faces with three equivalent Rb(1)Cl12 cuboctahedra, faces with four equivalent Rb(2)Cl12 cuboctahedra, faces with three equivalent Mn(2)Cl6 octahedra, and faces with four equivalent Mn(1)Cl6 octahedra. The corner-sharing octahedral tilt angles are 15°. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to three equivalent Cl(1) and three equivalent Cl(2) atoms to form MnCl6 octahedra that share corners with three equivalent Rb(2)Cl12 cuboctahedra, corners with three equivalent Mn(2)Cl6 octahedra, faces with three equivalent Rb(1)Cl12 cuboctahedra, faces with four equivalent Rb(2)Cl12 cuboctahedra, and  a faceface with one Mn(1)Cl6 octahedra. The corner-sharing octahedral tilt angles are 1°. In the second Mn site, Mn(2) is bonded to six equivalent Cl(1) atoms to form MnCl6 octahedra that share corners with six equivalent Mn(1)Cl6 octahedra, faces with two equivalent Rb(1)Cl12 cuboctahedra, and faces with six equivalent Rb(2)Cl12 cuboctahedra. The corner-sharing octahedral tilt angles are 1°. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted linear geometry to one Rb(1), three equivalent Rb(2), one Mn(1), and one Mn(2) atom. In the second Cl site, Cl(2) is bonded to two equivalent Rb(1), two equivalent Rb(2), and two equivalent Mn(1) atoms to form a mixture of distorted face and corner-sharing ClRb4Mn2 octahedra. The corner-sharing octahedral tilt angles range from 3-60°. is represented by the CIF card [CIF]
