Nb5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. In the second Nb site, Nb(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Nb(2) and five equivalent Nb(1) atoms.
Nb5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. There are a spread of Nb(1)-Ge(1) bond distances ranging from 2.65-2.90 Å. In the second Nb site, Nb(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. All Nb(2)-Ge(1) bond lengths are 2.73 Å. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Nb(2) and five equivalent Nb(1) atoms.
