The material structure described by Na3BN2 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent Na sites. In the first Na site, Na(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing NaN4 tetrahedra. In the second Na site, Na(2) is bonded in a 7-coordinate geometry to three equivalent B(1), two equivalent N(1), and two equivalent N(2) atoms. In the third Na site, Na(3) is bonded in a 6-coordinate geometry to two equivalent B(1), two equivalent N(1), and two equivalent N(2) atoms. B(1) is bonded in a linear geometry to two equivalent Na(3), three equivalent Na(2), one N(1), and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 1-coordinate geometry to two equivalent Na(1), two equivalent Na(2), two equivalent Na(3), and one B(1) atom. In the second N site, N(2) is bonded in a distorted single-bond geometry to two equivalent Na(1), two equivalent Na(2), two equivalent Na(3), and one B(1) atom. is represented by the CIF card [CIF]
