Materials Data on K5La2 by Materials Project

Abstract

K5La2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent K sites. In the first K site, K is bonded in a 12-coordinate geometry to six K and six equivalent La atoms. There are a spread of K–K bond distances ranging from 4.16–4.69 Å. There are a spread of K–La bond distances ranging from 4.25–4.79 Å. In the second K site, K is bonded in a 10-coordinate geometry to eight K and two equivalent La atoms. There are a spread of K–K bond distances ranging from 4.20–4.58 Å. Both K–La bond lengths are 4.81 Å. In the third K site, K is bonded in a 9-coordinate geometry to six K and three equivalent La atoms. The K–K bond length is 4.21 Å. There are a spread of K–La bond distances ranging from 4.35–4.61 Å. La is bonded in a 1-coordinate geometry to ten K and one La atom. The La–La bond length is 2.91 Å.
