KAuBr3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. K(1) is bonded to twelve 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 Au(1)Br6 octahedra. Au(1) is bonded to six equivalent Br(1) atoms to form AuBr6 octahedra that share corners with six equivalent Au(1)Br6 octahedra and faces with eight equivalent K(1)Br12 cuboctahedra. The corner-sharing octahedra are not tilted. Br(1) is bonded to four equivalent K(1) and two equivalent Au(1) atoms to form a mixture of edge, face, and corner-sharing BrK4Au2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
