The crystal structure described by Pt2CuAl is Tetraauricupride-derived structured and crystallizes in the tetragonal P4/mmm space group. Pt(1) is bonded in a distorted body-centered cubic geometry to four equivalent Cu(1) and four equivalent Al(1) atoms. Cu(1) is bonded to eight equivalent Pt(1) and four equivalent Al(1) atoms to form CuAl4Pt8 cuboctahedra that share corners with twelve equivalent Cu(1)Al4Pt8 cuboctahedra, edges with eight equivalent Al(1)Cu4Pt8 cuboctahedra, faces with four equivalent Al(1)Cu4Pt8 cuboctahedra, and faces with six equivalent Cu(1)Al4Pt8 cuboctahedra. Al(1) is bonded to eight equivalent Pt(1) and four equivalent Cu(1) atoms to form AlCu4Pt8 cuboctahedra that share corners with twelve equivalent Al(1)Cu4Pt8 cuboctahedra, edges with eight equivalent Cu(1)Al4Pt8 cuboctahedra, faces with four equivalent Cu(1)Al4Pt8 cuboctahedra, and faces with six equivalent Al(1)Cu4Pt8 cuboctahedra. is represented by the CIF card [CIF]
