Materials Data on Na(MoSe)3 by Materials Project

Na(MoSe)3 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Na is bonded in a 12-coordinate geometry to three Mo and nine Se atoms. All Na–Mo bond lengths are 3.66 Å. There are a spread of Na–Se bond distances ranging from 3.28–3.50 Å. There are three inequivalent Mo sites. In the first Mo site, Mo is bonded in a distorted see-saw-like geometry to one Na and four Se atoms. There are two shorter (2.64 Å) and two longer (2.72 Å) Mo–Se bond lengths. In the second Mo site, Mo is bonded in a distorted see-saw-like geometry to one Na and four Se atoms. There are two shorter (2.64 Å) and two longer (2.72 Å) Mo–Se bond lengths. In the third Mo site, Mo is bonded in a distorted see-saw-like geometry to one Na and four Se atoms. There are two shorter (2.64 Å) and two longer (2.72 Å) Mo–Se bond lengths. There are three inequivalent Se sites. In the first Se site, Se is bonded in a 7-coordinate geometry to three equivalent Na and four Mo atoms. In the second Se site, Se is bonded in a 7-coordinate geometry to three equivalent Na and four Mo atoms. In the third Se site, Se is bonded in a 7-coordinate geometry to three equivalent Na and four Mo atoms.
