Materials Data on HoGe2Pd by Materials Project

Abstract

HoPdGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ho is bonded in a 12-coordinate geometry to four equivalent Pd and ten Ge atoms. All Ho–Pd bond lengths are 3.17 Å. There are a spread of Ho–Ge bond distances ranging from 3.16–3.55 Å. Pd is bonded in a 9-coordinate geometry to four equivalent Ho and five Ge atoms. There are a spread of Pd–Ge bond distances ranging from 2.42–2.58 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Ho, one Pd, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.49 Å. In the second Ge site, Ge is bonded to four equivalent Ho and four equivalent Pd atoms to form a mixture of distorted edge and face-sharing GeHo4Pd4 tetrahedra.
