Materials Data on Nb3(Ni10B3)2 by Materials Project

Nb3(Ni10B3)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 Ni atoms. All Nb–Ni bond lengths are 2.47 Å. In the second Nb site, Nb is bonded in a distorted cuboctahedral geometry to twelve equivalent Ni atoms. All Nb–Ni bond lengths are 2.57 Å. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded to one Nb and three equivalent B atoms to form a mixture of distorted edge and corner-sharing NiNbB3 tetrahedra. All Ni–B bond lengths are 2.13 Å. In the second Ni site, Ni is bonded in a 2-coordinate geometry to one Nb and two equivalent B atoms. Both Ni–B bond lengths are 2.08 Å. B is bonded in a 8-coordinate geometry to eight Ni atoms.
