Materials Data on Nb2(Co7B2)3 by Materials Project
Nb2(Co7B2)3 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Nb is bonded in a distorted tetrahedral geometry to four equivalent Co atoms. All Nb–Co bond lengths are 2.43 Å. There are three inequivalent Co sites. In the first Co site, Co is bonded in a cuboctahedral geometry to twelve equivalent Co atoms. All Co–Co bond lengths are 2.51 Å. In the second Co site, Co is bonded to one Nb and three equivalent B atoms to form a mixture of distorted edge and corner-sharing CoNbB3 tetrahedra. All Co–B bond lengths are 2.08 Å. In the third Co site, Co is bonded in a distorted bent 150 degrees geometry to one Co and two equivalent B atoms. Both Co–B bond lengths are 2.09 Å. B is bonded in a 8-coordinate geometry to eight Co atoms.
