Materials Data on Nb3Ge by Materials Project
Nb3Ge crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are three inequivalent Nb sites. In the first Nb site, Nb is bonded in a 4-coordinate geometry to two equivalent Nb and four equivalent Ge atoms. Both Nb–Nb bond lengths are 2.85 Å. There are a spread of Nb–Ge bond distances ranging from 2.75–3.01 Å. In the second Nb site, Nb is bonded in a 4-coordinate geometry to two equivalent Nb and four equivalent Ge atoms. Both Nb–Nb bond lengths are 2.66 Å. All Nb–Ge bond lengths are 2.72 Å. In the third Nb site, Nb is bonded in a distorted q6 geometry to ten Nb atoms. Both Nb–Nb bond lengths are 2.66 Å. Ge is bonded in a 10-coordinate geometry to ten Nb atoms.
