Materials Data on Na2BN by Materials Project
Na2BN crystallizes in the orthorhombic Pbcm space group. The structure is one-dimensional and consists of two Na2BN ribbons oriented in the (1, 0, 0) direction. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a distorted single-bond geometry to one B3- atom. The Na–B bond length is 2.97 Å. In the second Na1+ site, Na1+ is bonded in a 4-coordinate geometry to two equivalent B3- atoms. Both Na–B bond lengths are 2.77 Å. B3- is bonded in a distorted bent 120 degrees geometry to three Na1+ and two equivalent N1+ atoms. Both B–N bond lengths are 1.43 Å. N1+ is bonded in a bent 120 degrees geometry to two equivalent B3- atoms.
