PaIn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pa(1) is bonded to twelve equivalent In(1) atoms to form PaIn12 cuboctahedra that share corners with twelve equivalent Pa(1)In12 cuboctahedra, edges with twenty-four equivalent In(1)Pa4In8 cuboctahedra, faces with six equivalent Pa(1)In12 cuboctahedra, and faces with twelve equivalent In(1)Pa4In8 cuboctahedra. In(1) is bonded to four equivalent Pa(1) and eight equivalent In(1) atoms to form InPa4In8 cuboctahedra that share corners with twelve equivalent In(1)Pa4In8 cuboctahedra, edges with eight equivalent Pa(1)In12 cuboctahedra, edges with sixteen equivalent In(1)Pa4In8 cuboctahedra, faces with four equivalent Pa(1)In12 cuboctahedra, and faces with fourteen equivalent In(1)Pa4In8 cuboctahedra.
