RbPdC4Br crystallizes in the tetragonal I4/mmm space group. Rb(1) is bonded in a rectangular see-saw-like geometry to four equivalent Br(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded to four equivalent C(1) and two equivalent Br(1) atoms to form corner-sharing PdC4Br2 octahedra. The corner-sharing octahedra are not tilted. In the second Pd site, Pd(2) is bonded to four equivalent C(2) and two Br(1,1) atoms to form corner-sharing PdC4Br2 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one Pd(1) and one C(2) atom. In the second C site, C(2) is bonded in a linear geometry to one Pd(2) and one C(1) atom. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded to four equivalent Rb(1), one Pd(1), and one Pd(2) atom to form a mixture of edge and corner-sharing BrRb4Pd2 octahedra. The corner-sharing octahedral tilt angles range from 0-2°. In the second Br site, Br(1) is bonded to four equivalent Rb(1), one Pd(1), and one Pd(2) atom to form a mixture of edge and corner-sharing BrRb4Pd2 octahedra. The corner-sharing octahedral tilt angles range from 0-2°.
