Materials Data on LaSe2 by Materials Project
LaSe2 crystallizes in the tetragonal P4/nmm 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 3.09–3.20 Å. There are two inequivalent Se+1.50- sites. In the first Se+1.50- site, Se+1.50- is bonded to five equivalent La3+ atoms to form a mixture of distorted corner and edge-sharing SeLa5 trigonal bipyramids. In the second Se+1.50- site, Se+1.50- is bonded in a 8-coordinate geometry to four equivalent La3+ atoms.
