Materials Data on Hf3(NbGe2)2 by Materials Project
Abstract
Hf3(NbGe2)2 is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Hf sites. In the first Hf site, Hf is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Hf–Ge bond distances ranging from 2.80–3.01 Å. In the second Hf site, Hf is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Hf–Ge bond distances ranging from 2.71–2.83 Å. Nb is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Nb–Ge bond distances ranging from 2.59–2.80 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four Hf, four equivalent Nb, and one Ge atom. The Ge–Ge bond length is 2.58 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to five Hf, three equivalent Nb, and one Ge atom. The Ge–Ge bond length is 2.78 Å. In the third Ge site, Ge is bonded in a 9-coordinate geometry to six Hf, two equivalent Nb, and one Ge atom.
