Materials Data on Nb5Ge3 by Materials Project

Abstract

Nb5Ge3 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Nb sites. In the first Nb site, Nb is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Nb–Ge bond distances ranging from 2.71–2.98 Å. In the second Nb site, Nb is bonded in a 6-coordinate geometry to two equivalent Nb and four equivalent Ge atoms. Both Nb–Nb bond lengths are 2.59 Å. All Nb–Ge bond lengths are 2.73 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to ten Nb atoms. In the second Ge site, Ge is bonded in a 10-coordinate geometry to eight equivalent Nb and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.59 Å.
