Materials Data on In2(Ni7B2)3 by Materials Project

Abstract

In2(Ni7B2)3 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are three inequivalent Ni sites. In the first Ni site, Ni is bonded to one In and three equivalent B atoms to form a mixture of distorted corner and edge-sharing NiInB3 tetrahedra. The Ni–In bond length is 2.50 Å. All Ni–B bond lengths are 2.08 Å. In the second Ni site, Ni is bonded in a distorted bent 150 degrees geometry to one Ni and two equivalent B atoms. The Ni–Ni bond length is 2.51 Å. Both Ni–B bond lengths are 2.09 Å. In the third Ni site, Ni is bonded in a cuboctahedral geometry to twelve equivalent Ni atoms. In is bonded in a distorted tetrahedral geometry to four equivalent Ni atoms. B is bonded in a 8-coordinate geometry to eight Ni atoms.
