The material described by K2PtBr6 crystallizes in the cubic Fm-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 four equivalent Pt(1)Br6 octahedra. Pt(1) is bonded to six equivalent Br(1) atoms to form PtBr6 octahedra that share faces with eight equivalent K(1)Br12 cuboctahedra. Br(1) is bonded to four equivalent K(1) and one Pt(1) atom to form a mixture of distorted edge, face, and corner-sharing BrK4Pt square pyramids. is represented by the CIF file [CIF]
