Materials Data on BaSe3 by Materials Project
BaSe3 is Barium trisulfide structured and crystallizes in the tetragonal P-42_1m space group. The structure is three-dimensional. Ba is bonded to twelve Se atoms to form a mixture of distorted face and corner-sharing BaSe12 cuboctahedra. There are a spread of Ba–Se bond distances ranging from 3.41–3.79 Å. There are two inequivalent Se sites. In the first Se site, Se is bonded in a 5-coordinate geometry to four equivalent Ba and one Se atom. The Se–Se bond length is 2.41 Å. In the second Se site, Se is bonded in a 2-coordinate geometry to four equivalent Ba and two equivalent Se atoms.
