Materials Data on Si4Ni9B2 by Materials Project
Abstract
Ni9B2Si4 crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. there are two inequivalent Ni+1.78+ sites. In the first Ni+1.78+ site, Ni+1.78+ is bonded in a 6-coordinate geometry to two equivalent B and four equivalent Si4- atoms. Both Ni–B bond lengths are 2.17 Å. There are a spread of Ni–Si bond distances ranging from 2.32–2.59 Å. In the second Ni+1.78+ site, Ni+1.78+ is bonded in a tetrahedral geometry to four equivalent Si4- atoms. All Ni–Si bond lengths are 2.25 Å. B is bonded in a 10-coordinate geometry to eight equivalent Ni+1.78+ and two equivalent B atoms. Both B–B bond lengths are 2.08 Å. Si4- is bonded in a 9-coordinate geometry to nine Ni+1.78+ atoms.
