TmAg3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Tm(1) is bonded to twelve equivalent Ag(1) atoms to form TmAg12 cuboctahedra that share corners with twelve equivalent Tm(1)Ag12 cuboctahedra, edges with twenty-four equivalent Ag(1)Tm4Ag8 cuboctahedra, faces with six equivalent Tm(1)Ag12 cuboctahedra, and faces with twelve equivalent Ag(1)Tm4Ag8 cuboctahedra. Ag(1) is bonded to four equivalent Tm(1) and eight equivalent Ag(1) atoms to form distorted AgTm4Ag8 cuboctahedra that share corners with twelve equivalent Ag(1)Tm4Ag8 cuboctahedra, edges with eight equivalent Tm(1)Ag12 cuboctahedra, edges with sixteen equivalent Ag(1)Tm4Ag8 cuboctahedra, faces with four equivalent Tm(1)Ag12 cuboctahedra, and faces with fourteen equivalent Ag(1)Tm4Ag8 cuboctahedra.
