Materials Data on PrYNi4 by Materials Project

Abstract

PrYNi4 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 Y and twelve equivalent Ni atoms. All Pr–Y bond lengths are 3.16 Å. All Pr–Ni bond lengths are 3.03 Å. Y is bonded in a 12-coordinate geometry to four equivalent Pr and twelve equivalent Ni atoms. All Y–Ni bond lengths are 3.02 Å. Ni is bonded to three equivalent Pr, three equivalent Y, and six equivalent Ni atoms to form a mixture of edge, corner, and face-sharing NiPr3Y3Ni6 cuboctahedra. There are three shorter (2.57 Å) and three longer (2.58 Å) Ni–Ni bond lengths.
