Materials Data on UInNi4 by Materials Project

Abstract

UNi4In is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. U is bonded in a 12-coordinate geometry to twelve equivalent Ni and four equivalent In atoms. All U–Ni bond lengths are 2.91 Å. All U–In bond lengths are 3.04 Å. Ni is bonded to three equivalent U, six equivalent Ni, and three equivalent In atoms to form a mixture of edge, face, and corner-sharing NiU3In3Ni6 cuboctahedra. There are three shorter (2.47 Å) and three longer (2.49 Å) Ni–Ni bond lengths. All Ni–In bond lengths are 2.91 Å. In is bonded in a 4-coordinate geometry to four equivalent U and twelve equivalent Ni atoms.
