Materials Data on Ho5Bi2Pd by Materials Project

Abstract

Ho5PdBi2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are four inequivalent Ho sites. In the first Ho site, Ho is bonded in a 5-coordinate geometry to one Pd and four equivalent Bi atoms. The Ho–Pd bond length is 2.86 Å. There are two shorter (3.21 Å) and two longer (3.22 Å) Ho–Bi bond lengths. In the second Ho site, Ho is bonded to one Pd and four equivalent Bi atoms to form distorted edge-sharing HoBi4Pd square pyramids. The Ho–Pd bond length is 2.97 Å. There are two shorter (3.17 Å) and two longer (3.19 Å) Ho–Bi bond lengths. In the third Ho site, Ho is bonded in a 5-coordinate geometry to one Pd and four equivalent Bi atoms. The Ho–Pd bond length is 2.86 Å. There are two shorter (3.25 Å) and two longer (3.28 Å) Ho–Bi bond lengths. In the fourth Ho site, Ho is bonded in a 2-coordinate geometry to two equivalent Pd and three equivalent Bi atoms. There are one shorter (2.91 Å) and one longer (2.97 Å) Ho–Pd bond lengths. There are a spread of Ho–Bi bond distances ranging from 3.33–3.59 Å. Pd is bonded in a 7-coordinate geometry to seven Ho atoms. Bi is bonded in a 9-coordinate geometry to nine Ho atoms.
