PmIn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pm(1) is bonded to twelve equivalent In(1) atoms to form PmIn12 cuboctahedra that share corners with twelve equivalent Pm(1)In12 cuboctahedra, edges with twenty-four equivalent In(1)Pm4In8 cuboctahedra, faces with six equivalent Pm(1)In12 cuboctahedra, and faces with twelve equivalent In(1)Pm4In8 cuboctahedra. In(1) is bonded to four equivalent Pm(1) and eight equivalent In(1) atoms to form distorted InPm4In8 cuboctahedra that share corners with twelve equivalent In(1)Pm4In8 cuboctahedra, edges with eight equivalent Pm(1)In12 cuboctahedra, edges with sixteen equivalent In(1)Pm4In8 cuboctahedra, faces with four equivalent Pm(1)In12 cuboctahedra, and faces with fourteen equivalent In(1)Pm4In8 cuboctahedra.
