Materials Data on HoGa4Ni by Materials Project

Abstract

HoNiGa4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ho is bonded in a 1-coordinate geometry to two equivalent Ni and thirteen Ga atoms. Both Ho–Ni bond lengths are 3.13 Å. There are a spread of Ho–Ga bond distances ranging from 2.90–3.39 Å. Ni is bonded in a 9-coordinate geometry to two equivalent Ho and seven Ga atoms. There are a spread of Ni–Ga bond distances ranging from 2.35–2.50 Å. There are three inequivalent Ga sites. In the first Ga site, Ga is bonded in a 12-coordinate geometry to three equivalent Ho, three equivalent Ni, and six Ga atoms. There are a spread of Ga–Ga bond distances ranging from 2.63–3.00 Å. In the second Ga site, Ga is bonded in a distorted linear geometry to three equivalent Ho, one Ni, and eight Ga atoms. All Ga–Ga bond lengths are 2.84 Å. In the third Ga site, Ga is bonded in a distorted q6 geometry to four equivalent Ho and six Ga atoms.
