Materials Data on PrYMg4 by Materials Project
Mg4PrY is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Mg is bonded to six equivalent Mg, three equivalent Pr, and three equivalent Y atoms to form a mixture of face, edge, and corner-sharing MgPr3Y3Mg6 cuboctahedra. All Mg–Mg bond lengths are 3.05 Å. All Mg–Pr bond lengths are 3.58 Å. All Mg–Y bond lengths are 3.58 Å. Pr is bonded in a 12-coordinate geometry to twelve equivalent Mg and four equivalent Y atoms. All Pr–Y bond lengths are 3.74 Å. Y is bonded in a 12-coordinate geometry to twelve equivalent Mg and four equivalent Pr atoms.
