The material structure described by Tm3In is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Tm(1) is bonded to eight equivalent Tm(1) and four equivalent In(1) atoms to form distorted TmTm8In4 cuboctahedra that share corners with twelve equivalent Tm(1)Tm8In4 cuboctahedra, edges with eight equivalent In(1)Tm12 cuboctahedra, edges with sixteen equivalent Tm(1)Tm8In4 cuboctahedra, faces with four equivalent In(1)Tm12 cuboctahedra, and faces with fourteen equivalent Tm(1)Tm8In4 cuboctahedra. In(1) is bonded to twelve equivalent Tm(1) atoms to form InTm12 cuboctahedra that share corners with twelve equivalent In(1)Tm12 cuboctahedra, edges with twenty-four equivalent Tm(1)Tm8In4 cuboctahedra, faces with six equivalent In(1)Tm12 cuboctahedra, and faces with twelve equivalent Tm(1)Tm8In4 cuboctahedra. is represented by the CIF card [CIF]
