RhAg3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Rh(1) is bonded to twelve equivalent Ag(1) atoms to form RhAg12 cuboctahedra that share corners with six equivalent Rh(1)Ag12 cuboctahedra, corners with twelve equivalent Ag(1)Ag8Rh4 cuboctahedra, edges with eighteen equivalent Ag(1)Ag8Rh4 cuboctahedra, faces with eight equivalent Rh(1)Ag12 cuboctahedra, and faces with twelve equivalent Ag(1)Ag8Rh4 cuboctahedra. Ag(1) is bonded to four equivalent Rh(1) and eight equivalent Ag(1) atoms to form distorted AgAg8Rh4 cuboctahedra that share corners with four equivalent Rh(1)Ag12 cuboctahedra, corners with fourteen equivalent Ag(1)Ag8Rh4 cuboctahedra, edges with six equivalent Rh(1)Ag12 cuboctahedra, edges with twelve equivalent Ag(1)Ag8Rh4 cuboctahedra, faces with four equivalent Rh(1)Ag12 cuboctahedra, and faces with sixteen equivalent Ag(1)Ag8Rh4 cuboctahedra.

There are six shorter (2.88 Å) and six longer (2.89 Å) Rh(1)-Ag(1) bond lengths. Ag(1) is bonded to four equivalent Rh(1) and eight equivalent Ag(1) atoms to form distorted AgAg8Rh4 cuboctahedra that share corners with four equivalent Rh(1)Ag12 cuboctahedra, corners with fourteen equivalent Ag(1)Ag8Rh4 cuboctahedra, edges with six equivalent Rh(1)Ag12 cuboctahedra, edges with twelve equivalent Ag(1)Ag8Rh4 cuboctahedra, faces with four equivalent Rh(1)Ag12 cuboctahedra, and faces with sixteen equivalent Ag(1)Ag8Rh4 cuboctahedra. There are a spread of Ag(1)-Ag(1) bond distances ranging from 2.87-2.92 Å.
