Materials Data on Fe2B7 by Materials Project
Abstract
Fe2B7 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are four inequivalent Fe sites. In the first Fe site, Fe is bonded to twelve B atoms to form a mixture of distorted edge and face-sharing FeB12 cuboctahedra. There are a spread of Fe–B bond distances ranging from 2.00–2.28 Å. In the second Fe site, Fe is bonded to twelve B atoms to form a mixture of distorted edge and face-sharing FeB12 cuboctahedra. There are a spread of Fe–B bond distances ranging from 1.97–2.28 Å. In the third Fe site, Fe is bonded in a 10-coordinate geometry to two equivalent Fe and ten B atoms. Both Fe–Fe bond lengths are 2.60 Å. There are a spread of Fe–B bond distances ranging from 2.06–2.28 Å. In the fourth Fe site, Fe is bonded in a 1-coordinate geometry to two equivalent Fe and twelve B atoms. There are a spread of Fe–B bond distances ranging from 1.95–2.68 Å. There are fourteen inequivalent B sites. In the first B site, B is bonded in a 7-coordinate geometry to two equivalent Fe and five B atoms. There are a spread of B–B bond distances ranging from 1.67–1.89 Å. In the secondmore »
