Materials Data on Co22B6Sb by Materials Project

Abstract

Co22B6Sb crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are three inequivalent Co sites. In the first Co site, Co is bonded in a distorted tetrahedral geometry to four equivalent Co atoms. All Co–Co bond lengths are 2.39 Å. In the second Co site, Co is bonded in a 3-coordinate geometry to one Co and three equivalent B atoms. All Co–B bond lengths are 2.07 Å. In the third Co site, Co is bonded in a 2-coordinate geometry to two equivalent B and one Sb atom. Both Co–B bond lengths are 2.14 Å. The Co–Sb bond length is 2.57 Å. B is bonded in a 8-coordinate geometry to eight Co atoms. Sb is bonded in a cuboctahedral geometry to twelve equivalent Co atoms.
