Materials Data on Nb3(Fe10B3)2 by Materials Project
Abstract
Nb3(Fe10B3)2 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Nb sites. In the first Nb site, Nb is bonded in a distorted tetrahedral geometry to four equivalent Fe atoms. All Nb–Fe bond lengths are 2.50 Å. In the second Nb site, Nb is bonded in a distorted cuboctahedral geometry to twelve equivalent Fe atoms. All Nb–Fe bond lengths are 2.63 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded in a distorted bent 150 degrees geometry to one Nb and two equivalent B atoms. Both Fe–B bond lengths are 2.13 Å. In the second Fe site, Fe is bonded to one Nb and three equivalent B atoms to form a mixture of distorted edge and corner-sharing FeNbB3 tetrahedra. All Fe–B bond lengths are 2.13 Å. B is bonded in a 8-coordinate geometry to eight Fe atoms.
