Materials Data on HfSiW by Materials Project
HfWSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Hf is bonded in a 9-coordinate geometry to four equivalent W and five equivalent Si atoms. There are two shorter (2.99 Å) and two longer (3.08 Å) Hf–W bond lengths. There are a spread of Hf–Si bond distances ranging from 2.73–2.91 Å. W is bonded in a 12-coordinate geometry to four equivalent Hf and four equivalent Si atoms. There are a spread of W–Si bond distances ranging from 2.53–2.70 Å. Si is bonded in a 9-coordinate geometry to five equivalent Hf and four equivalent W atoms.
