The material structure described by Co3V is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. V(1) is bonded to twelve Co(1,1) atoms to form VCo12 cuboctahedra that share corners with six equivalent V(1)Co12 cuboctahedra; corners with twelve Co(1,1)V4Co8 cuboctahedra; edges with eighteen Co(1,1)V4Co8 cuboctahedra; faces with eight equivalent V(1)Co12 cuboctahedra; and faces with twelve Co(1,1)V4Co8 cuboctahedra. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to four equivalent V(1) and eight Co(1,1) atoms to form CoV4Co8 cuboctahedra that share corners with four equivalent V(1)Co12 cuboctahedra; corners with fourteen Co(1,1)V4Co8 cuboctahedra; edges with six equivalent V(1)Co12 cuboctahedra; edges with twelve Co(1,1)V4Co8 cuboctahedra; faces with four equivalent V(1)Co12 cuboctahedra; and faces with sixteen Co(1,1)V4Co8 cuboctahedra. In the second Co site, Co(1) is bonded to four equivalent V(1) and eight equivalent Co(1) atoms to form CoV4Co8 cuboctahedra that share corners with four equivalent V(1)Co12 cuboctahedra; corners with fourteen Co(1,1)V4Co8 cuboctahedra; edges with six equivalent V(1)Co12 cuboctahedra; edges with twelve equivalent Co(1)V4Co8 cuboctahedra; faces with four equivalent V(1)Co12 cuboctahedra; and faces with sixteen Co(1,1)V4Co8 cuboctahedra. is represented by the CIF file [CIF]
