Title: Materials Data on LaSe2 by Materials Project

Abstract

LaSe2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La3+ is bonded in a 9-coordinate geometry to nine Se+1.50- atoms. There are a spread of La–Se bond distances ranging from 3.03–3.32 Å. There are two inequivalent Se+1.50- sites. In the first Se+1.50- site, Se+1.50- is bonded in a 5-coordinate geometry to four equivalent La3+ and one Se+1.50- atom. The Se–Se bond length is 2.52 Å. In the second Se+1.50- site, Se+1.50- is bonded to five equivalent La3+ atoms to form a mixture of distorted edge and corner-sharing SeLa5 trigonal bipyramids.
