YbNb3 crystallizes in the hexagonal P6_3/mmc space group. Yb(1) is bonded to twelve Nb(1,1,1) atoms to form a mixture of face and corner-sharing YbNb12 cuboctahedra. There are three inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a 12-coordinate geometry to four equivalent Yb(1) and eight Nb(1,1,1) atoms. In the second Nb site, Nb(1) is bonded in a 12-coordinate geometry to four equivalent Yb(1) and eight Nb(1,1) atoms. In the third Nb site, Nb(1) is bonded in a 12-coordinate geometry to four equivalent Yb(1) and eight Nb(1,1) atoms.
YbNb3 crystallizes in the hexagonal P6_3/mmc space group. Yb(1) is bonded to twelve Nb(1,1,1) atoms to form a mixture of face and corner-sharing YbNb12 cuboctahedra. There are six shorter (3.17 Å) and six longer (3.21 Å) Yb(1)-Nb(1,1,1) bond lengths. There are three inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a 12-coordinate geometry to four equivalent Yb(1) and eight Nb(1,1,1) atoms. There are a spread of Nb(1)-Nb(1,1,1) bond distances ranging from 2.80-3.53 Å. In the second Nb site, Nb(1) is bonded in a 12-coordinate geometry to four equivalent Yb(1) and eight Nb(1,1) atoms. There is one shorter (2.80 Å) and one longer (3.53 Å) Nb(1)-Nb(1) bond length. In the third Nb site, Nb(1) is bonded in a 12-coordinate geometry to four equivalent Yb(1) and eight Nb(1,1) atoms.
