Co3Ta is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ta(1) is bonded to twelve equivalent Co(1) atoms to form TaCo12 cuboctahedra that share corners with twelve equivalent Ta(1)Co12 cuboctahedra, edges with twenty-four equivalent Co(1)Ta4Co8 cuboctahedra, faces with six equivalent Ta(1)Co12 cuboctahedra, and faces with twelve equivalent Co(1)Ta4Co8 cuboctahedra. Co(1) is bonded to four equivalent Ta(1) and eight equivalent Co(1) atoms to form CoTa4Co8 cuboctahedra that share corners with twelve equivalent Co(1)Ta4Co8 cuboctahedra, edges with eight equivalent Ta(1)Co12 cuboctahedra, edges with sixteen equivalent Co(1)Ta4Co8 cuboctahedra, faces with four equivalent Ta(1)Co12 cuboctahedra, and faces with fourteen equivalent Co(1)Ta4Co8 cuboctahedra.
