The structure described by Pt5AlP crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to two equivalent Pt(2), two equivalent Al(1), and two equivalent P(1) atoms to form distorted PtAl2P2Pt2 tetrahedra that share corners with four equivalent Pt(2)Al4Pt8 cuboctahedra, corners with four equivalent Al(1)Pt12 cuboctahedra, corners with twelve equivalent Pt(1)Al2P2Pt2 tetrahedra, edges with two equivalent Pt(2)Al4Pt8 cuboctahedra, edges with two equivalent Al(1)Pt12 cuboctahedra, edges with seven equivalent Pt(1)Al2P2Pt2 tetrahedra, and faces with five equivalent Pt(1)Al2P2Pt2 tetrahedra. In the second Pt site, Pt(2) is bonded to eight equivalent Pt(1) and four equivalent Al(1) atoms to form distorted PtAl4Pt8 cuboctahedra that share corners with four equivalent Pt(2)Al4Pt8 cuboctahedra, corners with sixteen equivalent Pt(1)Al2P2Pt2 tetrahedra, edges with eight equivalent Pt(1)Al2P2Pt2 tetrahedra, faces with four equivalent Pt(2)Al4Pt8 cuboctahedra, and faces with four equivalent Al(1)Pt12 cuboctahedra. Al(1) is bonded to four equivalent Pt(2) and eight equivalent Pt(1) atoms to form AlPt12 cuboctahedra that share corners with four equivalent Al(1)Pt12 cuboctahedra, corners with sixteen equivalent Pt(1)Al2P2Pt2 tetrahedra, edges with eight equivalent Pt(1)Al2P2Pt2 tetrahedra, faces with four equivalent Pt(2)Al4Pt8 cuboctahedra, and faces with four equivalent Al(1)Pt12 cuboctahedra. P(1) is bonded in a body-centered cubic geometry to eight equivalent Pt(1) atoms. is represented by the CIF card [CIF]
