RuAg3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Ru(1) is bonded to twelve equivalent Ag(1) atoms to form RuAg12 cuboctahedra that share corners with six equivalent Ru(1)Ag12 cuboctahedra, corners with twelve equivalent Ag(1)Ag8Ru4 cuboctahedra, edges with eighteen equivalent Ag(1)Ag8Ru4 cuboctahedra, faces with eight equivalent Ru(1)Ag12 cuboctahedra, and faces with twelve equivalent Ag(1)Ag8Ru4 cuboctahedra. Ag(1) is bonded to four equivalent Ru(1) and eight equivalent Ag(1) atoms to form AgAg8Ru4 cuboctahedra that share corners with four equivalent Ru(1)Ag12 cuboctahedra, corners with fourteen equivalent Ag(1)Ag8Ru4 cuboctahedra, edges with six equivalent Ru(1)Ag12 cuboctahedra, edges with twelve equivalent Ag(1)Ag8Ru4 cuboctahedra, faces with four equivalent Ru(1)Ag12 cuboctahedra, and faces with sixteen equivalent Ag(1)Ag8Ru4 cuboctahedra.
