The structure described by Pt8V crystallizes in the tetragonal I4/mmm space group. V(1) is bonded to four equivalent Pt(2) and eight equivalent Pt(1) atoms to form VPt12 cuboctahedra that share corners with eight equivalent Pt(1)V2Pt10 cuboctahedra, faces with two equivalent V(1)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)V2Pt10 cuboctahedra. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to two equivalent V(1), four equivalent Pt(1), and six equivalent Pt(2) atoms to form distorted PtV2Pt10 cuboctahedra that share corners with two equivalent V(1)Pt12 cuboctahedra, corners with four equivalent Pt(1)V2Pt10 cuboctahedra, edges with twelve equivalent Pt(1)V2Pt10 cuboctahedra, faces with three equivalent V(1)Pt12 cuboctahedra, and faces with seven equivalent Pt(1)V2Pt10 cuboctahedra. In the second Pt site, Pt(2) is bonded in a distorted single-bond geometry to one V(1) and six equivalent Pt(1) atoms. is represented by the CIF file [CIF]
