Abstract

Rb3OI is (Cubic) Perovskite-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a linear geometry to two O2- and four I1- atoms. There are one shorter (2.80 Å) and one longer (2.83 Å) Rb–O bond lengths. There are a spread of Rb–I bond distances ranging from 4.03–4.13 Å. In the second Rb1+ site, Rb1+ is bonded in a distorted L-shaped geometry to two equivalent O2- and four I1- atoms. Both Rb–O bond lengths are 2.74 Å. There are two shorter (4.03 Å) and two longer (4.14 Å) Rb–I bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to six Rb1+ atoms to form ORb6 octahedra that share corners with three equivalent IRb12 cuboctahedra, corners with three equivalent ORb6 octahedra, faces with seven IRb12 cuboctahedra, and a faceface with one ORb6 octahedra. The corner-sharing octahedral tilt angles are 2°. In the second O2- site, O2- is bonded to six equivalent Rb1+ atoms to form ORb6 octahedra that share corners with six equivalent ORb6 octahedra and faces with eight IRb12 cuboctahedra.
