Rh3W is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. W(1) is bonded to twelve equivalent Rh(1) atoms to form WRh12 cuboctahedra that share corners with six equivalent W(1)Rh12 cuboctahedra, corners with twelve equivalent Rh(1)Rh8W4 cuboctahedra, edges with eighteen equivalent Rh(1)Rh8W4 cuboctahedra, faces with eight equivalent W(1)Rh12 cuboctahedra, and faces with twelve equivalent Rh(1)Rh8W4 cuboctahedra. Rh(1) is bonded to four equivalent W(1) and eight equivalent Rh(1) atoms to form RhRh8W4 cuboctahedra that share corners with four equivalent W(1)Rh12 cuboctahedra, corners with fourteen equivalent Rh(1)Rh8W4 cuboctahedra, edges with six equivalent W(1)Rh12 cuboctahedra, edges with twelve equivalent Rh(1)Rh8W4 cuboctahedra, faces with four equivalent W(1)Rh12 cuboctahedra, and faces with sixteen equivalent Rh(1)Rh8W4 cuboctahedra.

There are six shorter (2.69 Å) and six longer (2.74 Å) W(1)-Rh(1) bond lengths. Rh(1) is bonded to four equivalent W(1) and eight equivalent Rh(1) atoms to form RhRh8W4 cuboctahedra that share corners with four equivalent W(1)Rh12 cuboctahedra, corners with fourteen equivalent Rh(1)Rh8W4 cuboctahedra, edges with six equivalent W(1)Rh12 cuboctahedra, edges with twelve equivalent Rh(1)Rh8W4 cuboctahedra, faces with four equivalent W(1)Rh12 cuboctahedra, and faces with sixteen equivalent Rh(1)Rh8W4 cuboctahedra. There are four shorter (2.69 Å) and four longer (2.74 Å) Rh(1)-Rh(1) bond lengths.
