description: RbCsMn2Cl6 is (Cubic) Perovskite-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded to twelve Cl1- atoms to form CsCl12 cuboctahedra that share corners with two equivalent RbCl12 cuboctahedra, corners with four equivalent CsCl12 cuboctahedra, corners with six MnCl6 octahedra, faces with four CsCl12 cuboctahedra, faces with four equivalent RbCl12 cuboctahedra, and faces with six MnCl6 octahedra. The corner-sharing octahedral tilt angles are 14°. There are a spread of Cs–Cl bond distances ranging from 3.67–3.78 Å. In the second Cs1+ site, Cs1+ is bonded to twelve Cl1- atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent RbCl12 cuboctahedra, faces with six equivalent CsCl12 cuboctahedra, and faces with eight MnCl6 octahedra. There are six shorter (3.70 Å) and six longer (3.72 Å) Cs–Cl bond lengths. There are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded to twelve Cl1- atoms to form RbCl12 cuboctahedra that share corners with six equivalent CsCl12 cuboctahedra, corners with six equivalent MnCl6 octahedra, faces with eight RbCl12 cuboctahedra, and faces with six equivalent MnCl6 octahedra. The corner-sharing octahedral tilt angles are 14°. There are six shorter (3.63 Å) and six longer (3.76 Å) Rb–Cl bond lengths. In the second Rb1+ site, Rb1+ is bonded to twelve Cl1- atoms to form RbCl12 cuboctahedra that share corners with four equivalent CsCl12 cuboctahedra, corners with eight equivalent RbCl12 cuboctahedra, faces with two equivalent RbCl12 cuboctahedra, faces with four equivalent CsCl12 cuboctahedra, and faces with eight MnCl6 octahedra. There are a spread of Rb–Cl bond distances ranging from 3.64–3.69 Å. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to six Cl1- atoms to form MnCl6 octahedra that share a cornercorner with one RbCl12 cuboctahedra, corners with two equivalent CsCl12 cuboctahedra, corners with three MnCl6 octahedra, faces with three CsCl12 cuboctahedra, faces with four RbCl12 cuboctahedra, and a faceface with one MnCl6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are a spread of Mn–Cl bond distances ranging from 2.54–2.56 Å. In the second Mn2+ site, Mn2+ is bonded to six Cl1- atoms to form MnCl6 octahedra that share corners with three equivalent CsCl12 cuboctahedra, corners with three equivalent MnCl6 octahedra, faces with three equivalent RbCl12 cuboctahedra, faces with four CsCl12 cuboctahedra, and a faceface with one MnCl6 octahedra. The corner-sharing octahedral tilt angles are 1°. All Mn–Cl bond lengths are 2.55 Å. There are seven inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 6-coordinate geometry to two equivalent Cs1+, two equivalent Rb1+, and two equivalent Mn2+ atoms. In the second Cl1- site, Cl1- is bonded in a distorted linear geometry to one Cs1+, three Rb1+, and two equivalent Mn2+ atoms. The Cl–Cs bond length is 3.70 Å. In the third Cl1- site, Cl1- is bonded in a 6-coordinate geometry to three Cs1+, one Rb1+, and two equivalent Mn2+ atoms. In the fourth Cl1- site, Cl1- is bonded in a distorted linear geometry to one Cs1+, three Rb1+, and two equivalent Mn2+ atoms. Both Cl–Rb bond lengths are 3.69 Å. Both Cl–Mn bond lengths are 2.54 Å. In the fifth Cl1- site, Cl1- is bonded in a distorted linear geometry to three Cs1+, one Rb1+, and two Mn2+ atoms. In the sixth Cl1- site, Cl1- is bonded in a 6-coordinate geometry to four Rb1+ and two equivalent Mn2+ atoms. In the seventh Cl1- site, Cl1- is bonded in a distorted linear geometry to one Cs1+, three Rb1+, and two equivalent Mn2+ atoms. Both Cl–Mn bond lengths are 2.54 Å.
