The compound described by Yb3Nb is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Yb(1) is bonded to eight equivalent Yb(1) and four equivalent Nb(1) atoms to form distorted YbYb8Nb4 cuboctahedra that share corners with four equivalent Nb(1)Yb12 cuboctahedra, corners with fourteen equivalent Yb(1)Yb8Nb4 cuboctahedra, edges with six equivalent Nb(1)Yb12 cuboctahedra, edges with twelve equivalent Yb(1)Yb8Nb4 cuboctahedra, faces with four equivalent Nb(1)Yb12 cuboctahedra, and faces with sixteen equivalent Yb(1)Yb8Nb4 cuboctahedra. Nb(1) is bonded to twelve equivalent Yb(1) atoms to form NbYb12 cuboctahedra that share corners with six equivalent Nb(1)Yb12 cuboctahedra, corners with twelve equivalent Yb(1)Yb8Nb4 cuboctahedra, edges with eighteen equivalent Yb(1)Yb8Nb4 cuboctahedra, faces with eight equivalent Nb(1)Yb12 cuboctahedra, and faces with twelve equivalent Yb(1)Yb8Nb4 cuboctahedra. is represented by the CIF card [CIF]
