Materials Data on Ho2Al by Materials Project
AlHo2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 5-coordinate geometry to five equivalent Al atoms. There are a spread of Ho–Al bond distances ranging from 3.06–3.41 Å. In the second Ho site, Ho is bonded in a 3-coordinate geometry to five equivalent Al atoms. There are a spread of Ho–Al bond distances ranging from 3.14–3.54 Å. Al is bonded in a 10-coordinate geometry to ten Ho atoms.
