The material structure described by KAgBr3 crystallizes in the trigonal R3c space group. K(1) is bonded in a distorted q6 geometry to nine equivalent Br(1) atoms. Ag(1) is bonded to six equivalent Br(1) atoms to form corner-sharing AgBr6 octahedra. The corner-sharing octahedral tilt angles are 18°. Br(1) is bonded to three equivalent K(1) and two equivalent Ag(1) atoms to form a mixture of distorted corner and edge-sharing BrK3Ag2 square pyramids. is represented by the CIF card [CIF]
