The crystal structure described by CsVBr3 crystallizes in the hexagonal P6_3/mmc space group. Cs(1) is bonded to twelve equivalent Br(1) atoms to form CsBr12 cuboctahedra that share corners with six equivalent Cs(1)Br12 cuboctahedra, corners with six equivalent V(1)Br6 octahedra, faces with eight equivalent Cs(1)Br12 cuboctahedra, and faces with six equivalent V(1)Br6 octahedra. The corner-sharing octahedral tilt angles are 17°. V(1) is bonded to six equivalent Br(1) atoms to form VBr6 octahedra that share corners with six equivalent Cs(1)Br12 cuboctahedra, faces with six equivalent Cs(1)Br12 cuboctahedra, and faces with two equivalent V(1)Br6 octahedra. Br(1) is bonded to four equivalent Cs(1) and two equivalent V(1) atoms to form a mixture of distorted edge, face, and corner-sharing BrCs4V2 octahedra. The corner-sharing octahedral tilt angles range from 0-71°. is represented by the Crystallographic Information File (CIF) [CIF]
