The material structure described by Co3Pt is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to eight Co(1,1) and four equivalent Pt(1) atoms to form distorted CoCo8Pt4 cuboctahedra that share corners with four equivalent Pt(1)Co12 cuboctahedra; corners with fourteen Co(1,1)Co8Pt4 cuboctahedra; edges with six equivalent Pt(1)Co12 cuboctahedra; edges with twelve Co(1,1)Co8Pt4 cuboctahedra; faces with four equivalent Pt(1)Co12 cuboctahedra; and faces with sixteen Co(1,1)Co8Pt4 cuboctahedra. In the second Co site, Co(1) is bonded to eight equivalent Co(1) and four equivalent Pt(1) atoms to form distorted CoCo8Pt4 cuboctahedra that share corners with four equivalent Pt(1)Co12 cuboctahedra; corners with fourteen Co(1,1)Co8Pt4 cuboctahedra; edges with six equivalent Pt(1)Co12 cuboctahedra; edges with twelve equivalent Co(1)Co8Pt4 cuboctahedra; faces with four equivalent Pt(1)Co12 cuboctahedra; and faces with sixteen Co(1,1)Co8Pt4 cuboctahedra. Pt(1) is bonded to twelve Co(1,1) atoms to form PtCo12 cuboctahedra that share corners with six equivalent Pt(1)Co12 cuboctahedra; corners with twelve equivalent Co(1)Co8Pt4 cuboctahedra; edges with eighteen Co(1,1)Co8Pt4 cuboctahedra; faces with eight equivalent Pt(1)Co12 cuboctahedra; and faces with twelve Co(1,1)Co8Pt4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
