The material described by KAgBr3 is (Cubic) Perovskite structured and crystallizes in the monoclinic Cm space group. K(1) is bonded to four equivalent Br(2) and eight equivalent Br(1) atoms to form KBr12 cuboctahedra that share corners with twelve equivalent K(1)Br12 cuboctahedra, faces with six equivalent K(1)Br12 cuboctahedra, and faces with eight equivalent Ag(1)Br6 octahedra. Ag(1) is bonded to two equivalent Br(2) and four equivalent Br(1) atoms to form AgBr6 octahedra that share corners with six equivalent Ag(1)Br6 octahedra and faces with eight equivalent K(1)Br12 cuboctahedra. The corner-sharing octahedral tilt angles are 1°. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded to four equivalent K(1) and two equivalent Ag(1) atoms to form a mixture of distorted face, corner, and edge-sharing BrK4Ag2 octahedra. The corner-sharing octahedral tilt angles range from 1-61°. In the second Br site, Br(2) is bonded to four equivalent K(1) and two equivalent Ag(1) atoms to form a mixture of distorted face, corner, and edge-sharing BrK4Ag2 octahedra. The corner-sharing octahedral tilt angles range from 1-61°. is represented by the Crystallographic Information File (CIF) [CIF]
