Materials Data on La7Ni3 by Materials Project

Abstract

La7Ni3 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are three inequivalent La sites. In the first La site, La is bonded in a distorted water-like geometry to two equivalent Ni atoms. Both La–Ni bond lengths are 2.84 Å. In the second La site, La is bonded in a 3-coordinate geometry to three equivalent Ni atoms. All La–Ni bond lengths are 2.96 Å. In the third La site, La is bonded in a 3-coordinate geometry to three equivalent Ni atoms. There are two shorter (2.92 Å) and one longer (3.04 Å) La–Ni bond lengths. Ni is bonded in a 6-coordinate geometry to six La atoms.
