The material structure described by TaPt3 is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. Ta(1) is bonded to four equivalent Pt(2) and eight equivalent Pt(1) atoms to form TaPt12 cuboctahedra that share corners with two equivalent Ta(1)Pt12 cuboctahedra, corners with eight equivalent Pt(1)Ta4Pt8 cuboctahedra, edges with six equivalent Ta(1)Pt12 cuboctahedra, edges with twelve equivalent Pt(1)Ta4Pt8 cuboctahedra, faces with six equivalent Ta(1)Pt12 cuboctahedra, and faces with eight equivalent Pt(1)Ta4Pt8 cuboctahedra. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to four equivalent Ta(1), four equivalent Pt(1), and four equivalent Pt(2) atoms to form distorted PtTa4Pt8 cuboctahedra that share corners with four equivalent Ta(1)Pt12 cuboctahedra, corners with ten equivalent Pt(1)Ta4Pt8 cuboctahedra, edges with six equivalent Ta(1)Pt12 cuboctahedra, edges with six equivalent Pt(1)Ta4Pt8 cuboctahedra, faces with four equivalent Ta(1)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)Ta4Pt8 cuboctahedra. In the second Pt site, Pt(2) is bonded in a distorted see-saw-like geometry to four equivalent Ta(1) and eight equivalent Pt(1) atoms. is represented by the CIF card [CIF]
