Materials Data on Ho2(CoNi)5 by Materials Project
Abstract
Ho2(CoNi)5 crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 6-coordinate geometry to six Co and twelve Ni atoms. There are four shorter (2.83 Å) and two longer (2.86 Å) Ho–Co bond lengths. There are eight shorter (3.14 Å) and four longer (3.15 Å) Ho–Ni bond lengths. In the second Ho site, Ho is bonded in a 6-coordinate geometry to ten Co and eight equivalent Ni atoms. There are a spread of Ho–Co bond distances ranging from 2.81–3.15 Å. All Ho–Ni bond lengths are 3.14 Å. There are three inequivalent Co sites. In the first Co site, Co is bonded in a 12-coordinate geometry to three Ho, two equivalent Co, and four equivalent Ni atoms. Both Co–Co bond lengths are 2.40 Å. All Co–Ni bond lengths are 2.44 Å. In the second Co site, Co is bonded in a 12-coordinate geometry to three Ho and six Ni atoms. There are four shorter (2.42 Å) and two longer (2.43 Å) Co–Ni bond lengths. In the third Co site, Co is bonded to four equivalent Ho, four equivalent Co, and four equivalent Ni atomsmore »
