Materials Data on CsGeI3 by Materials Project
CsGeI3 is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent I1- atoms to form CsI12 cuboctahedra that share corners with twelve equivalent CsI12 cuboctahedra, faces with six equivalent CsI12 cuboctahedra, and faces with eight equivalent GeI6 octahedra. There are a spread of Cs–I bond distances ranging from 4.26–4.41 Å. Ge2+ is bonded to six equivalent I1- atoms to form GeI6 octahedra that share corners with six equivalent GeI6 octahedra and faces with eight equivalent CsI12 cuboctahedra. The corner-sharing octahedral tilt angles are 12°. There are three shorter (2.80 Å) and three longer (3.34 Å) Ge–I bond lengths. I1- is bonded in a 6-coordinate geometry to four equivalent Cs1+ and two equivalent Ge2+ atoms.
