PtIn3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. Pt(1) is bonded to four equivalent In(2) and eight equivalent In(1) atoms to form PtIn12 cuboctahedra that share corners with four equivalent Pt(1)In12 cuboctahedra, corners with eight equivalent In(2)In8Pt4 cuboctahedra, edges with eight equivalent Pt(1)In12 cuboctahedra, edges with sixteen equivalent In(1)In8Pt4 cuboctahedra, faces with four equivalent Pt(1)In12 cuboctahedra, faces with six equivalent In(2)In8Pt4 cuboctahedra, and faces with eight equivalent In(1)In8Pt4 cuboctahedra. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent Pt(1), four equivalent In(1), and four equivalent In(2) atoms to form distorted InIn8Pt4 cuboctahedra that share corners with twelve equivalent In(1)In8Pt4 cuboctahedra, edges with eight equivalent Pt(1)In12 cuboctahedra, edges with eight equivalent In(1)In8Pt4 cuboctahedra, edges with eight equivalent In(2)In8Pt4 cuboctahedra, faces with four equivalent Pt(1)In12 cuboctahedra, faces with four equivalent In(2)In8Pt4 cuboctahedra, and faces with ten equivalent In(1)In8Pt4 cuboctahedra. In the second In site, In(2) is bonded to four equivalent Pt(1) and eight equivalent In(1) atoms to form distorted InIn8Pt4 cuboctahedra that share corners with four equivalent In(2)In8Pt4 cuboctahedra, corners with eight equivalent Pt(1)In12 cuboctahedra, edges with eight equivalent In(2)In8Pt4 cuboctahedra, edges with sixteen equivalent In(1)In8Pt4 cuboctahedra, faces with four equivalent In(2)In8Pt4 cuboctahedra, faces with six equivalent Pt(1)In12 cuboctahedra, and faces with eight equivalent In(1)In8Pt4 cuboctahedra.
