RbCr3Pd crystallizes in the trigonal R3m space group. Rb(1) is bonded in a 12-coordinate geometry to twelve equivalent Cr(1) atoms. There are a spread of Rb(1)-Cr(1) bond distances ranging from 3.08-4.21 Å. Cr(1) is bonded in a 1-coordinate geometry to four equivalent Rb(1) and two equivalent Pd(1) atoms. There is one shorter (2.18 Å) and one longer (2.98 Å) Cr(1)-Pd(1) bond length. Pd(1) is bonded to six equivalent Cr(1) atoms to form corner-sharing PdCr6 octahedra. The corner-sharing octahedra are not tilted.
