Materials Data on HoGe2Pd by Materials Project
HoPdGe2 crystallizes in the orthorhombic Immm 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 six equivalent Pd and eight Ge atoms. There are four shorter (3.22 Å) and two longer (3.30 Å) Ho–Pd bond lengths. There are a spread of Ho–Ge bond distances ranging from 3.01–3.08 Å. In the second Ho site, Ho is bonded in a 8-coordinate geometry to four equivalent Pd and ten Ge atoms. All Ho–Pd bond lengths are 3.24 Å. There are a spread of Ho–Ge bond distances ranging from 3.26–3.39 Å. Pd is bonded in a 10-coordinate geometry to five Ho and five Ge atoms. There are a spread of Pd–Ge bond distances ranging from 2.49–2.68 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Ho, two equivalent Pd, and one Ge atom. The Ge–Ge bond length is 2.43 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to four Ho, three equivalent Pd, and one Ge atom. The Ge–Ge bond length is 2.66 Å. In the third Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Ho, two equivalent Pd, and one Ge atom. The Ge–Ge bond length is 2.43 Å.
