Materials Data on Ho3(SiNi3)2 by Materials Project

Abstract

Ho3(Ni3Si)2 crystallizes in the cubic Im-3m space group. The structure is three-dimensional. Ho is bonded in a 12-coordinate geometry to eight equivalent Ni and four equivalent Si atoms. There are four shorter (2.81 Å) and four longer (2.92 Å) Ho–Ni bond lengths. All Ho–Si bond lengths are 3.10 Å. Ni is bonded in a 12-coordinate geometry to four equivalent Ho, four equivalent Ni, and two equivalent Si atoms. All Ni–Ni bond lengths are 2.52 Å. Both Ni–Si bond lengths are 2.40 Å. Si is bonded to six equivalent Ho and six equivalent Ni atoms to form a mixture of corner and face-sharing SiHo6Ni6 cuboctahedra.
