Materials Data on Ba(MoSe)3 by Materials Project
Ba(MoSe)3 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Ba is bonded in a 9-coordinate geometry to nine Se atoms. There are a spread of Ba–Se bond distances ranging from 3.43–3.49 Å. There are three inequivalent Mo sites. In the first Mo site, Mo is bonded in a distorted see-saw-like geometry to four Se atoms. There are a spread of Mo–Se bond distances ranging from 2.68–2.75 Å. In the second Mo site, Mo is bonded in a distorted see-saw-like geometry to four Se atoms. There are a spread of Mo–Se bond distances ranging from 2.68–2.75 Å. In the third Mo site, Mo is bonded in a distorted see-saw-like geometry to four Se atoms. There are two shorter (2.68 Å) and two longer (2.74 Å) Mo–Se bond lengths. There are three inequivalent Se sites. In the first Se site, Se is bonded to three equivalent Ba and four Mo atoms to form a mixture of distorted corner, edge, and face-sharing SeBa3Mo4 hexagonal pyramids. In the second Se site, Se is bonded to three equivalent Ba and four Mo atoms to form a mixture of distorted corner, edge, and face-sharing SeBa3Mo4 hexagonal pyramids. In the third Se site, Se is bonded to three equivalent Ba and four Mo atoms to form a mixture of distorted corner, edge, and face-sharing SeBa3Mo4 hexagonal pyramids.
