Materials Data on Pr2Ga by Materials Project
Pr2Ga is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 4-coordinate geometry to five equivalent Ga atoms. There are a spread of Pr–Ga bond distances ranging from 3.20–3.72 Å. In the second Pr site, Pr is bonded in a 5-coordinate geometry to five equivalent Ga atoms. There are a spread of Pr–Ga bond distances ranging from 3.23–3.49 Å. Ga is bonded in a 10-coordinate geometry to ten Pr atoms.
