Materials Data on Ho2Ga3Ni by Materials Project

Abstract

Ho2NiGa3 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 12-coordinate geometry to three equivalent Ni and nine Ga atoms. There are one shorter (3.15 Å) and two longer (3.20 Å) Ho–Ni bond lengths. There are a spread of Ho–Ga bond distances ranging from 2.98–3.25 Å. In the second Ho site, Ho is bonded in a 12-coordinate geometry to three equivalent Ni and nine Ga atoms. All Ho–Ni bond lengths are 3.02 Å. There are a spread of Ho–Ga bond distances ranging from 2.99–3.36 Å. Ni is bonded in a 10-coordinate geometry to six Ho and four Ga atoms. There are a spread of Ni–Ga bond distances ranging from 2.45–2.70 Å. There are three inequivalent Ga sites. In the first Ga site, Ga is bonded in a 10-coordinate geometry to six Ho, one Ni, and three Ga atoms. There are two shorter (2.61 Å) and one longer (2.90 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 10-coordinate geometry to six Ho, two equivalent Ni, and two Ga atoms. The Ga–Ga bond length is 2.66 Å. In the third Ga site, Ga is bonded in a 10-coordinate geometry to six Ho, one Ni, and three Ga atoms.
