In the ninth B+0.33- site, B+0.33- is bonded in a trigonal planar geometry to three Se+0.11- atoms. There are a spread of B–Se bond distances ranging from 1.94–2.00 Å. There are nine inequivalent Se+0.11- sites. In the first Se+0.11- site, Se+0.11- is bonded in a 5-coordinate geometry to four Na1+ and one B+0.33- atom.

In the third Se+0.11- site, Se+0.11- is bonded in a 4-coordinate geometry to two Na1+ and two B+0.33- atoms. In the fourth Se+0.11- site, Se+0.11- is bonded in a 5-coordinate geometry to four Na1+ and one B+0.33- atom. In the fifth Se+0.11- site, Se+0.11- is bonded in a 2-coordinate geometry to two Na1+ and two B+0.33- atoms. In the sixth Se+0.11- site, Se+0.11- is bonded in a 2-coordinate geometry to two Na1+ and two B+0.33- atoms. In the seventh Se+0.11- site, Se+0.11- is bonded in a 4-coordinate geometry to two Na1+ and two B+0.33- atoms. In the eighth Se+0.11- site, Se+0.11- is bonded in a 3-coordinate geometry to two Na1+ and two B+0.33- atoms. In the ninth Se+0.11- site, Se+0.11- is bonded in a 3-coordinate geometry to two equivalent Na1+ and two B+0.33- atoms.« less
