Materials Data on Hf3Sb by Materials Project

Abstract

Hf3Sb crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. there are three inequivalent Hf sites. In the first Hf site, Hf is bonded in a distorted water-like geometry to two equivalent Sb atoms. There are one shorter (2.92 Å) and one longer (3.05 Å) Hf–Sb bond lengths. In the second Hf site, Hf is bonded in a 3-coordinate geometry to three equivalent Sb atoms. There are a spread of Hf–Sb bond distances ranging from 2.88–3.10 Å. In the third Hf site, Hf is bonded in a 4-coordinate geometry to four equivalent Sb atoms. There are a spread of Hf–Sb bond distances ranging from 2.91–2.95 Å. Sb is bonded in a 9-coordinate geometry to nine Hf atoms.
