Materials Data on HfSiRh by Materials Project

HfRhSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Hf is bonded in a 11-coordinate geometry to six equivalent Rh and five equivalent Si atoms. There are a spread of Hf–Rh bond distances ranging from 2.93–3.04 Å. There are three shorter (2.79 Å) and two longer (2.80 Å) Hf–Si bond lengths. Rh is bonded in a 4-coordinate geometry to six equivalent Hf and four equivalent Si atoms. There are a spread of Rh–Si bond distances ranging from 2.44–2.50 Å. Si is bonded in a 9-coordinate geometry to five equivalent Hf and four equivalent Rh atoms.
