Materials Data on CePrFe4 by Materials Project
PrCeFe4 is Cubic Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Pr is bonded in a 12-coordinate geometry to four equivalent Ce and twelve equivalent Fe atoms. All Pr–Ce bond lengths are 3.20 Å. All Pr–Fe bond lengths are 3.07 Å. Ce is bonded in a 12-coordinate geometry to four equivalent Pr and twelve equivalent Fe atoms. All Ce–Fe bond lengths are 3.07 Å. Fe is bonded to three equivalent Pr, three equivalent Ce, and six equivalent Fe atoms to form a mixture of edge, face, and corner-sharing FeCe3Pr3Fe6 cuboctahedra. There are three shorter (2.61 Å) and three longer (2.63 Å) Fe–Fe bond lengths.
