Materials Data on Ho3Ni2 by Materials Project

Abstract

Ho3Ni2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are three inequivalent Ho sites. In the first Ho site, Ho is bonded in an octahedral geometry to six equivalent Ni atoms. All Ho–Ni bond lengths are 2.90 Å. In the second Ho site, Ho is bonded in a 6-coordinate geometry to six equivalent Ni atoms. There are three shorter (2.75 Å) and three longer (2.90 Å) Ho–Ni bond lengths. In the third Ho site, Ho is bonded in a 5-coordinate geometry to five equivalent Ni atoms. There are a spread of Ho–Ni bond distances ranging from 2.81–3.30 Å. Ni is bonded in a 9-coordinate geometry to eight Ho and one Ni atom. The Ni–Ni bond length is 2.53 Å.
